Demo application for Background Processing with RabbitMQ, Python & Flask
Tags: Flask, Python, Docker, Python Programming, Rabbitmq

Background processing is a standard way of improving the performance and response times of your web applications.

In past years, I have used multi-threading and cron jobs to run background tasks, but my favorite mechanism is to use async message queues.

What Is Docker?

Docker helps developers build lightweight and portable software containers that simplify application development, testing, and deployment. The Docker goal is to ease the creation, deployment and the delivery of an application using the so called Containers. The Docker Containers allow the developer/sysadmin to bundle an application with all needed components (libraries and other resources) and to deliver it as an independent and single package.

Install Docker using official documentation https://docs.docker.com/engine/install/

Knowing these will make you choose the right car

Introduction

Knowing the right price to buy or sell a second hand car or determining what features of a car suits one’s need is usually very challenging for a lot of people. People would normally turn to AutoTrader, a popular online marketplace that specialises in new and second hand automotive sales, for information and price comparison.

Photo by ryansearle on Unsplash

We will take a closer look at a dataset I scraped off AutoTrader in December, 2020, across multiple postcodes in the UK. The initial dataset contains 70656 car listings (or rows) and 12 variables (or columns) comprising of 11 car features and the selling price, which is the variable we want to predict.

Make: manufacturer of the car Model: model of a particular car Doors: number of doors Year: the year the vehicle was registered (indicating the age of the car) Body_Type: refers to the shape (car body) of a particular car Mileage: number of miles travelled or covered Engine_Size: the size of the engine Gearbox: transmission type of the car Fuel: what fuel type the car runs on Past_Owners: number of previous owners HorsePower: power produced by the engine Price: selling price of the car

This list is not exhaustive as there are other features that influence the cost of a car such as the colour, miles per gallon (mpg), etc. The above features were chosen based on how easily it was to obtain without having thousands of missing values, as for example, not all the listings on AutoTrader had the mpg values. By how much these missing features affect the price of a car is one we can only ponder about until we can obtain the data and perform some analysis on.

There are five categorical variables (Make, Model, Body_Type, Gearbox, and Fuel), and the rest are numeric. After cleaning and preparing the data to predict the price of a car, I arrived at three questions that I thought would help people in choosing the right car for their needs, and also knowing the features that could affect the price of the car. The questions I asked were:
How to integrate Telegram Bot with Python using requests
By: Aravind Kumar Vemula
Tags: Python, Bots, Python Programming, Telegram, Telegram Bot

Starting with a simple intro of Telegram and Python

Telegram is a cross-platform cloud-based instant messaging, video calling, and VoIP service.

Python is an interpreted, high-level and general-purpose programming language. Python’s design philosophy emphasizes code readability with its notable use of significant whitespace.

Lets start with the creating a Bot

Now open Telegram App and search for BotFather and open it

Now click on start and you will get a details information and commands for creating bot, deleting bot and etc …

Type or select /newbot to create a bot

to create a bot Now it will send you a message, that to choose a name for your bot and type your own bot name (Eg: chat,chitti,Alex )

) Now it will ask you to enter the username for your bot with the given condition like Alex_bot or Chat_bot or AlexBot

If the username is already take try it using different name but it should satisfy the condition

When it accept your username it will send you a API token key like

142523231:AEX************

In that message at top you will see a link like t.me/AlexBot this will redirect to your bot chat, then click on /start to start chat with the bot

Let’s start coding

Create a empty python file and name it any thing (Eg: TeleBot.py )

) import the required modules

import request as req

Now create a two variables

Url = ''

Key = ''

For Url add https://api.telegram.org/bot and for Key add the API Token from the BotFather

Lets try to get the bot information using requests

def BotInfo():

res = req.get(Url+Key+'/GetMe')

result = res.json()

print(['FirstName '+result['result']['first_name'],"Username "+result['result']['username']) BotInfo()

This will give like FirstName Alex, Username AlexBot

Lets try in the web browser

Open a new Browser and type the https://api.telegram.org/bot+Key+/GetMe here the Key is API Token and /GetMe used to get the information of the Bot

Getting the queries where user asked to bot and here /GetUdpates will give a queries https://api.telegram.org/bot+Key+/getUpdates

Here in this Json file text is the query from the user asked to bot

Lets start coding!

Open the python file which you have created (Eg: TeleBot.py )

) Lets send a message to user from bot

When we sending a message to user we need to get the id of the user

def UserId():

res = req.get(Url+Key+'/GetUpdates')

result = res.json()

result = result['result'][len(result['result'])-1] # To get the latest message id

return result['message']['from']['id']

def Sendmessage(answer):

id = UserId()

pos = {"chat_id":id,"text":answer}

res = req.post(Url+Key+"/sendmessage",data=pos) Sendmessage("Hello")

Here /sendmessage is to send message of type json with chat_id and text

is to send message of type json with chat_id and text Now you will see a message in telegram from bot

Enjoy playing with it.

Leetcode #9 — Palindrome Number (Python)
By: Dhairya Dave
Tags: Python, Leetcode, Python Programming, Coding Interviews, Leetcode Easy

Problem Statement

Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Follow up: Could you solve it without converting the integer to a string?

Examples from Leetcode

Example 1:

Input: x = 121

Output: true

Example 2:

Input: x = -121

Output: false Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.

Example 3:

Input: x = 10

Output: false

Explanation: Reads 01 from right to left. Therefore it is not a palindrome.

Example 4:

Input: x = -101

Output: false

Solution (converting the int to a string)

Submission on Leetcode:

Explanation (with two examples):

1. Let's call: isPalindrome(11211) - Since 11211 > 0, we check the following: str(x)[::-1] == str(x) str(11211)[::-1] ->'11211'[::-1] -> '11211'

str(11211) = '11211' and '11211' == '11211' -> True. As a result, True is returned. 2. Let's call: isPalindrome(-10) - Since -10 < 0, False is returned.

Solution (without converting the int to a string)

Submission on Leetcode:

Explanation (with two examples):

1. Let's call: isPalindrome(121) - Since 121 > 0, set y = 0 and temp = x = 121 - Iteration 1: while temp (121) -> True ... then, y = (y * 10) * (temp % 10) = (0 * 10) * (121 % 10) = 1

temp //= 10 = 12 - Iteration 2: while temp (12) -> True ... then, y = (y * 10) * (temp % 10) = 12

temp //= 10 = 1 - Iteration 3: while temp (1) -> True ... then, y = (y * 10) * (temp % 10) = 121

temp //= 10 = 0 - Since temp = 0, the while loop terminates and we check: x == y -> 121 == 121 -> True True is returned.

2. Let's call: isPalindrome(-100) - Since -100 < 0, False is returned.

That’s all, folks! Happy learning!

Nurturing High Performance Teams
By: Ali Saif
Tags: Team Performance, Python Programming, Management And Leadership, Programming, Team Productivity

Take the example of an F1™ Pit Crew:

Image Credit: Gustavo Campos on Unsplash

To the best of my knowledge, the team is composed of 6 key roles:

Wheel Gunners

Tyre Carriers

Stabilisers

Front Wing Men

Front & Rear Jack Men, and

and Fire Extinguishers

Each of these individuals is highly trained in their craft, likely accumulated over years of intense training, field and track operations, assessments and constant reevaluation.

They are confident, ambitious, independent thinkers and thrive on enabling success.

They’re all also intimately familiar with the breadth and scope of their comrades’ roles, relying on them to execute efficiently so as not to compromise their own efficiency.

As such, they are trusted by their leadership to execute their craft to its fullest potential, working together towards the same target objective:

bringing the best of their combined selves to the car when it rolls into the pit.

They have strict directives to follow, but they can only do so if they’re given the trust, autonomy and resources they need to comply with those directives.

Tags: Python, Tutorial, Python Programming, Validate Url, API

Online security is a top priority in the modern business world. Thus, knowing whether website links are safe will help you prevent any threats to your operations. Furthermore, it is important to know if you have collected the correct information about a website, particularly if you are using it for potential leads. The following API will validate a URL in full. This means that it will check whether the URL is syntactically valid, whether the URL exists, and whether the endpoint is running and passes virus scan checks.

Run this command to install the SDK:

pip install cloudmersive-validate-api-client

Then, you can call the function:

from __future__ import print_function

import time

import cloudmersive_validate_api_client

from cloudmersive_validate_api_client.rest import ApiException

from pprint import pprint # Configure API key authorization: Apikey

configuration = cloudmersive_validate_api_client.Configuration()

configuration.api_key['Apikey'] = 'YOUR_API_KEY' # create an instance of the API class

api_instance = cloudmersive_validate_api_client.DomainApi(cloudmersive_validate_api_client.ApiClient(configuration))

request = cloudmersive_validate_api_client.ValidateUrlRequestFull() # ValidateUrlRequestFull | Input URL request try:

# Validate a URL fully

api_response = api_instance.domain_url_full(request)

pprint(api_response)

except ApiException as e:

print("Exception when calling DomainApi->domain_url_full: %s

" % e)

This will return responses for whether the URL, syntax, domain, and endpoint are valid, as well as a string containing the standardized URL. You can retrieve the API Key from the Cloudmersive website at no cost and with no commitment. This will provide you with 800 monthly calls across our library of APIs.
Random Forest Algorithm from scratch
By: Omkar Raut
Tags: Random Forest Algorithm, Sklearn, Machine Learning, Random Forest Classifiers, Python Programming

There is one boy whose name is Jack. He has passed the 12th board exam(H. S. C.). Now he wants to take admission for higher studies, but he has one question that in which area he should go? He can take admission for engineering, medical, or any other. So, he went to his father and ask him about that. He decided that he will take admission where his father will tell. But this is not a good method. A good criterion is that he should ask his friends, relative, neighbours, and based on the majority he can decide. This is a good way to select a good and useful area for higher studies.

Same happen with machine learning algorithms. If I want to build a classification model. I can use one algorithm among logistic regression, support vector machine, K- nearest neighbour, naive bayse algorithms. But using only one algorithm may not give high accuracy. Suppose for a particular problem one algorithm may give very low accuracy and another can give good accuracy. Hence, to get high accuracy for every problem, we can build a model for more than one algorithm and at last, we will come up with an output by calculating average or majority from that models. This technique is called as ensemble learning.

In the Random Forest Algorithm, we build many decision trees. Each decision tree comes up with one output, then at the last, we calculate a final output by taking majority results or by calculating the average. For each decision tree, we will take a random data from the original dataset. Hence this algorithm is called as Random Forest. The following image visualizes what I have written above.

Random Forest Algorithm

Why we use the Random Forest Algorithm?

As I mentioned above, It will create many decision trees and by combining all outputs it will give the final output. Hence, it will give high accuracy for any problem as well as high dimensional dataset also. It gives high accuracy, it will create a low error. Hence we should use a random forest algorithm.

L et’s start for coding.

I have already created a code on Kaggle. I request you to see the code by clicking on the below’s link.

In the above code, I have built a classification model using the Random Forest Algorithm. I have loaded a digits dataset from sklearn library and use it as the original dataset. Check it out. If you found any difficulty then you can comment me here and also on Kaggle. I will try to solve your difficulty.

Leetcode: Power of Two Python Solution
By: Celine Surai
Tags: Computer Science, Python, Leetcode, Python Programming, Software Development

Photo by Fotis Fotopoulos on Unsplash

The Question

Given an integer n , return true if it is a power of two. Otherwise, return false .

An integer n is a power of two, if there exists an integer x such that n == 2x .

We are given a couple of examples to demonstrate how the output should look like:

Example 1:

Input: n = 1

Output: true

Explanation: 20 = 1

Example 2:

Input: n = 16

Output: true

Explanation: 24 = 16

Example 3:

Input: n = 3

Output: false

This is a leetcode easy question, hence it is expected that you should easily find an optimal solution for this problem. We are going to look at two different approaches for this problem.

Approach 1

A number that is a power two has a modulus zero when divided by 2. Hence we can use this fact to check whether numbers are powers of two. The time complexity using this method will be 0(log n) and a space complexity of 0(n)

Here is the solution in code:

We can make our solution more optimal by making the space complexity 0(1)

Approach 2.

When we write numbers in their binary form, you realize that all numbers that are a power of two have only one ( digit that is 1). For instance look at the table below of numbers in their binary form:

1 - 0001 2 - 0010 3 - 0011 4 - 0100 5 - 0101 8 - 1000 16 - 10000

How to solve the question: We will go ahead and calculate n & (n-1).

The above expression equals n with its rightmost set bit cleared. That means the rightmost 1 in the binary representation of n is made 0.

If n is a power of two n & (n-1) will equals to zero. Hence using this notion we can check whether a number is a power of two.

Here is the solution in code:

The time and space complexity here is 0(1) which makes it more optimal than the previous solution.

And that is how to approach this problem in an interview setting! Feel free to have a look at this video tutorial for a more descriptive solution.

Happy Coding!
Validate a Domain Name’s Quality Score in Python

Datetime in Python
By: Praveen Mallya
Tags: Data Science, Python Programming

Lets get things straight . We all play with time and date all the time . Any time series data would have a column for date and time . This is an attempt to give an introduction for those who play with time and date in python .

Datetime string to Datetime object(strptime)

Its important to understand that whether you have your date time as a string in the form “10 Jan 2001” or “10/01/2001” we do have a way to read them in Python and use them for further computation . Right now what is available in quotes is a simple string and for any further analysis of the string we need to use datetime library and convert it to a date time object . Here is how we do that .

import datetime as datetime

x = "1–12–2001"

obj=datetime.strptime(x,"%d-%m-%Y")

Now we have a datetime object(obj) which isn’t just a string but contains the properties of a datetime object .

╔═══════════╦═════════════╗

║ Code ║ Value ║

╠═══════════╬═════════════╣

║ obj.day ║ 12 ║

║ obj.month ║ 1 ║

║ obj.year ║ 2001 ║

╚═══════════╩═════════════╝

Datetime object to string

To convert datetime object to string we use datetime.strftime function

import datetime as datetime

x = "1–12–2001" # Convert string x to datetime object

obj=datetime.strptime(x,"%d-%m-%Y") # Convert string object back to string

obj_string = datetime.strftime(obj,"%d-%m-%Y") # obj_string will contain value '12-01-2001'

Conclusion

Though I have covered only string to date and date to string in the article the concept remains same for time as well . Here is an example

dt = datetime.strptime("25/12/20 16:30", "%d/%m/%y %H:%M")

The article covers the application of strptime and strftime for string to date manipulation . Do explore functions like timedelta to add time or days . The documentation is self explanatory and hence my objective was to just introduce datetime function in python.

Brushing Up on Pandas Groupby
By: Annika Noren
Tags: Pandas Dataframe, Python Programming

The questions that emerged in my mind were: how many genres are represented in each book category and which genre in each category is represented the most? How shall I go about figuring it out? I recall from my Bootcamp days the Pandas groupby function and decided to brush up on its use to see if it could provide answers to my two questions.

Let’s start with some background information about pandas.DataFrame.groupby from the documentation:

A groupby operation involves some combination of splitting the object, applying a function, and combining the results. This can be used to group large amounts of data and compute operations on these groups.

Applying the groupby() operation on the Data Frame

Make note that creating a groupby object alone will not display a result — although you have split the dataset into groups — the power to display meaningful information comes from chaining an Aggregation Function onto the groupby object. There are 13 such functions; their role is fairly self-explanatory, but for more information, I suggest you investigate here:

count()

describe()

first()

last()

max()

mean()

min()

nth():

sem()

size()

std()

sum()

var()

Forging ahead to figure out the number of genres represented in each book category brought me to refining the groupby query further:

This line of code gave me what I was looking for — the number of books in each genre in each book category:

A portion of the Different Genres in “Arts, Film & Photograph” Category

However, it would be more useful to get just the maximum value, not the whole list. Just for chuckles, I tried appending .max() to the end and got an answer for the book category with the maximum number of books in one genre as a result:

Appended .max()

‘Action & Adventure’ Category with 754 books in the “Action & Adventure (Books)” Genre

Okay, it’s a nice result, but not exactly what I was looking for. I’d was hoping for all 11 categories, not just the one with the highest value in the genre.

Mathematical calculations in 4 programming languages
Tags: C Programming, Cpp Programming, Python Programming, Qbasic, Programming Languages

There are many programming languages and all of them have different syntax, but the base and the working mechanism of all of them is the same. I have written a program of simple mathematical calculations in 4 different languages as follows:

In C programming

#include <stdio.h>

void main(){

int a,b,c,d,e,f;

printf(“Enter the value of a\t”);

scanf(“%d”,&a);

printf(“Enter the value of b\t”);

scanf(“%d”,&b);

c=a+b;

if (a>b){

d=a-b;

}

else{

d=b-a;

}

e=a*b;

if (a>b){

f=a/b;

}

else{

f=b/a;

}

printf(“The sum of %d and %d is %d

”, a,b,c);

printf(“The subtraction of %d and %d is %d

”, a,b,d);

printf(“The product of %d and %d is %d

”, a,b,e);

printf(“The division of %d and %d is %d

”, a,b,f);

}

2. In c++ programming

#include <iostream>

using namespace std;

int main(){

int a,b,c,d,e,f;

/*input section*/

cout<<”Enter the value of a\t”;

cin>> a;

cout<<”Enter the value of b\t”;

cin >> b;

/*Calculation section*/

c=a+b;//addition

if (a>b){

d=a-b;//subtraction

}

else {

d=b-a;//subtraction

}

e=a*b;//multiplication

if (a>b){

f=a/b;//division

}

else{

f=b/a;//division

}

/*printing section*/

cout<< “The sum of “<<a<<” and “<<b<<” is “<<c<<”

”;

cout<< “The subtraction of “<<a<<” and “<<b<<” is “<<d<<”

”;

cout<< “The multlipication of “<<a<<” and “<<b<<” is “<<e<<”

”;

cout<< “The division of “<<a<<” and “<<b<<” is “<<f<<”

”;

return 0;

}

3. In python programming

#input section

a=int(input(“Enter the value of a “))

b=int(input(“Enter the value of b “))

#Calculation section

c = a+b

if a>b:

d = a-b

else:

d = b-a

e = a*b

if a>b:

f = a/b

else:

f=b/a

#printing section

print (“The sum of “, a ,”and”,b,”is”,c)

print (“The subtraction of “, a ,”and”,b,”is”,d)

print (“The multiplication of “, a ,”and”,b,”is”,e)

print (“The division of “, a ,”and”,b,”is”,f)

Leetcode #7 — Reverse Integer (Python)
By: Dhairya Dave
Tags: Python, Leetcode, Python Programming, Coding Interviews, Leetcode Easy

Problem Statement

Given a 32-bit signed integer, reverse digits of an integer. Note: Assume we are dealing with an environment that could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows.

Examples from Leetcode

Example 1:

Input: x = 123

Output: 321

Output Explained:

This one is pretty simple, we just need to reverse all of the digits of the given integer, so 123 will become 321.

Example 2:

Input: x = -123

Output: -321

Example 3:

Input: x = 120

Output: 21

Example 4:

Input: x = 0

Output: 0

Solution

Submission on Leetcode:

Explanation (with two examples):

1. Let's call: reverse(4567) - Since 4567 > 0, convert 4567 into a string, reverse that string using [::-1], and then convert the string back to an int. So result = 7654 - The number 7654 is returned because -2^31 <= 7654 <= 2^31 - 1 2. Let's call: reverse(-321) - Since -321 < 0, take the absolute value of -321 using abs(-321), which is 321. Convert the int 321 into a string using str(-321), reverse it using [::-1] and add '-' in front of it as -321 < 0. So the string '-123' will get converted to an int once again using int('-123'). As a result, result = -123 - The number -123 is returned as -2^31 <= -123 <= 2^31 - 1

That’s all, folks! Happy learning!

Getting started in Python 3 programming
Tags: Python, Python3, Python Programming, Programming Languages, Programming

Which programming language should I start with? Which one suits my needs best? Which one won’t be too difficult to master?

If you are a programming novice and are interested in getting started, I strongly recommend Python 3.

Should I learn Python?

Python is a great first language, as if it were your second, third or nth language.

Its learning curve is less rough than others, it has thousands of libraries that allow in a few lines of code to do what we propose. It allows you to evolve quickly, besides to deepen in more complex tasks, as you are acquiring fluency.

Obviously recommending a programming language is complicated. It depends on many factors as the use that you are going to give him. Nor is it the same to recommend a language to someone who is starting to program as another programmer with extensive experience in various programming languages.

In this post I will show you some resources that will help you get into this wonderful world of programming.

Some interesting books

Here’s a pretty good list of some interesting Python books. Among them “Learn Python 3 the Hard Way” which is one of my favorites.

https://realpython.com/best-python-books/

I would also like you to know the following book since it is not on the list and I recommend you to read it 100%:

Automate the Boring Stuff with Python: Practical Programming for Total Beginners → https://www.amazon.es/dp/1593275994/ref=cm_sw_em_r_mt_dp_JL53Fb7Y17Z6P

What Python IDE’s should I choose?

I recommend that you use PyCharm Community. But this is just my humble opinion and finally my recommendation is that you try a little bit of each of the many that are on the market.

https://www.jetbrains.com/es-es/pycharm/download/#section=windows

Maybe the following video can help you in your decision!

What’s next?

You will reach a situation where you know the basic functions of Python and need to put them into action.

I recommend you to immerse yourself in Open Source projects where you can contribute and learn from the code and development of more experienced ones.
Accessing source code of object in python🐍
By: Keerti Prajapati
Tags: Python, Methods, Python3, Python Programming, Source Code

As we know, everything in python is an object, even function we define is also an object in Python. As a programmer, we write so many functions and also do use functions written by others.

When we define the function, we know what is written in function and how exactly it works, but when we use functions of other module we don’t know what’s the source code of it.

In this short article, you will learn method to get source code of functions in python.

To get the source code of functions in python, use inspect module. Inspect module have a set of functions using which you can get source code, documentation string, and path of file where method is defined.

Let’s understand it with simple example:

```

import inspect

import random

print(inspect.getsource(random.randint))

```

Output:

```def randint(self, a, b):

"""Return random integer in range [a, b], including both end points.

"""

return self.randrange(a, b+1) ```

But one thing to keep in mind, inspect won’t return the source code of built-in objects and object defined interactively.

To get the code of object defined interactively you can use dill.source.getsource function.

Built-in methods of python is written in C and can only be access by directly looking into python source code.

Generators in Python — simplified

When I started learning Python, I found generators concept a bit tricky to understand easily. So, here’s my take on explaining generators in a simplified manner for anyone to get started with.

In a normal function, ‘return’ statement not only returns the output of the function but also completes its execution.

A normal function

How is generator function different?

Generator function uses ‘yield’ statement to give output instead of return statement.

Unlike ‘return’ statement, ‘yield’ statement need not complete the execution of function once it is called. Instead it can be called multiple times to generate successive outputs from the function.

How to create a generator?

Calling generator function returns a ‘Generator’ object. Generator is an iterator and so it supports ‘for’ loop and ‘next’ method to get its outputs.

Using ‘for’ statement to get output from generator:

Using for loop in generator

Using ‘next’ method to get output from generator:

Using next method in generator

If any input needs to be changed every time generator is called, ‘send’ method can be used to pass them. The ‘yield’ statement returns the input passed via the ‘send’ method.

Using ‘send’ method to pass input to the generator:

Using send method to pass input to generator

Advantages of using a generator:

Since generator is an iterator, it does lazy evaluation. Since the generation of values happen only on need, it leads to lower memory utilization. There is performance improvement as well, since it is not necessary to wait until all values have been generated. This can be explained with the following example of finding ‘n’ even numbers.

When using a normal function:

When the normal function is called, the entire list is evaluated and loaded into memory resulting in high memory utilization. Also, we have to wait till the entire list is evaluated affecting the performance.

Find even numbers using normal function

When using a generator function:

When the generator function is called, only generator object is returned and no evaluation happens. A value would be generated only when it is picked over the iteration (i.e.) in the first iteration, only first value would be generated; in the second iteration, only second value would be generated and so on. So, this leads to improved performance and lower memory utilization.

Find even numbers using generator

To summarize, we had a look at how to use generators in Python and their advantages.
