Flask -> FastAPI

I'm happy with Flask and do not see the need to switch to FastAPI. Change my mind & (ideally) point me to a nice tutorial that does just that in a demo project.

Making a list of advanced topics in Python

I'm preparing for a technical interview. I failed the first one a week ago. I noticed the excercises were tagged as (advanced python). 2 coding questions, one from decorators and the other from SQL. I'm taking a month to prepare for my second chance at it. And I'm making a list of advanced topics/concepts in python. I don't want to be taken by surprise again. List comprehension Anonymous function Decorators Generators Exception handling Inheritance Encapsulation Unit testing Regex I need suggestions just in case I'm missing anything. I do practice coding excercises on hackerank.

Port scanning with Python

Lately I've been learning a bit about communicating over a network with Python and thought it might be fun to create a simple TCP port scanner. Had a lot of fun playing around with this on my home network. The full project write up and code can be found [here](https://sheldonbarry.com/2022/04/24/port-scanning-with-python/).

2-Button UI engine in MicroPython with "Apps" on a TTGO T-Display

https://youtu.be/wR3AkhD0nEg More of a demo than anything at this point, but I've got working text entry, menus, loadable apps(any file named app_AppName.py is detected as an app). I also have sleep modes, and wakelock-like functionality(Including modem sleep), and the ability for one app to launch another, with arguments and return values. In screen-off sleep mode, it uses 6mA without Wi-Fi(The USB chip and charge led takes some power, probably more like 0.5mA on battery). With Wi-Fi it's around 7mA with spikes every few seconds. With the screen on, you get 45mA with spikes up to 65mA. Probably room to improve that. But I'm impressed by the low power capabilities of MP(Once you add some assorted pull requests from the internet). The Calculator app actually just launches the text entry app, and evals the text you enter. There's a stopwatch and a tally counter, and a settings menu where you can customize things like the colors, and set an app to auto-load as soon as it boots up. In the future, I'll add password protection to prevent exiting the default app, and I'd like to eventually have some kind of mobile "App store" Android app for uploading new content, and maybe the ability to configure WiFi/MDNS/MQTT from the settings menu. The original idea for this was to be a replacement for Logitech's Harmony remotes. I think it would be awesome to have an open source home automation remote, that used an app-capable OS, that could also be a replacement for smart wall switches. Another fun thing I'd like to do is some kind of programming feature, so you could edit the logic for a little robot just with a 2 or 3 button menu. If MicroPython ever gets BLE bonding, making a wireless keyboard emulator for media or presentations might be another fun app.

Anyone know the history of why strings are iterable?

I think every intermediate Python programmer has had to learn the gotcha that you can't really duck-type iterables, because if you accidentally iterate over a string, Python will chug along perfectly fine despite it almost certainly not being the intended behavior. Even worse, because of the way collections ABCs are defined, a typing check like `isinstance("a string", collections.abc.Collection)` will still return True despite it almost certainly not being what is intended. My question is whether anyone knows *the history* of why this is the case. Given the direction that the language was moving in, I would've thought it'd be a prime candidate for removal in the 2-to-3 transition. Obviously, there are use cases for iterating along elements of a string, but with Python 3 strings being unicode-by-default, the rich standard library, and the general high-level nature of the language, I don't see much of a use case at all. Certainly, I don't think it's contentious to say the drawbacks of making it the default behavior outweigh the benefits, with any real use cases easily accommodated by more specific `str.characters` or `str.bytes` methods. So, what gives? Has this issue ever been actively discussed in the development of the language? Is it just a case of a holdover from earlier languages that was never really a big enough deal to get challenged? And why was it made even more formal with the introduction of `collections.abc`? Google-ing hasn't really provided any strong answers, so any stories or nuggets of info greatly appreciated! **edit:** Maybe should have made it more clear that the question is really why strings are *still* iterable by default. I understand the history of strings as character arrays, and don't have a hard time imagining how that naturally made it into the language. But why that is still the case in Python 3 given that: * It is a gotcha new users frequently run into (just search for people asking how to properly handle a `str` vs a `[str]` in a function argument) * It doesn't *really* fit with how we think about the datatypes in Python (I doubt many Python programmers day-to-day think of a `str` as "an ordered collection of `str` objects") * The uses for iterable-by-default seem limited given the wide builtin and standard library functionality available for `str` objects.

Speeding up python CLI's!

so yesterday I was trying to make a python CLI that needed to be fast. no matter what I did (`python -S`, pyinstaller, cx_freeze, bytecode compiling) it wouldnt be as fast as I needed it and some even made it slower like cx_freeze. well I found a way to make running it much much faster (nearly instantaneous). by using an asynchronous socket server and using netcat as input, you can give input to the server and recieve output immediately, since the script is already running it works for windows and linux, but you may need cygwin on windows unless there is a built in timeout and netcat command I do not know about how it works (on linux) is you define a bash function with this: `hithere(){ printf "$@" | timeout 0.1 nc 127.0.0.1 50200; }` and run the script: `python pyspeedtest.py` to send input you run `hithere Mum` and you get `hi, Mum` pyspeedtest.py ``` import pyspeed class myhandler(pyspeed.pyspeed_handler): def handle_request(self, *argv): return f"hi, {argv[1]}" handle = myhandler() handle.run() ``` pyspeed.py ```python import asyncio, socket class pyspeed_handler: async def run_server(self, address, port, handle): server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server.bind((address, port)) server.listen(8) server.setblocking(False) loop = asyncio.get_event_loop() while True: client, _ = await loop.sock_accept(server) loop.create_task(handle(client)) async def handle_client(self, client): loop = asyncio.get_event_loop() request = None try: while request != 'quit': request = (await loop.sock_recv(client, 255)).decode('utf8') response = self.handle_request(*([''] + str(request).split(' '))) + '\n' await loop.sock_sendall(client, response.encode('utf8')) client.close() except BrokenPipeError: pass def handle_request(self, *argv): return ''.join(argv) def run(self, address="localhost", port=50200): asyncio.run(self.run_server(address, port, self.handle_client)) ``` ```

I made my first Discord Bot with Python!

Hello everyone! Over the past 2 weeks I have been working on Discord Bot using [discord.py](https://discord.py) and Python! Inspired by r/place I decided to make a simple bot where users and place pixels on a large canvas. Commands include: $add\_pixel: Add a pixel to the grid at a specified coordinate and rgb color value $playback: Create a video showing the full canvas history $ban: Bans a user from placing new pixels (Admin only) $unban: Unbans a user allowing them to place pixels again (Admin only) One of the reasons I started with project was to learn how to use the MongoDB database as well as learn discord.py Here is a small example of the bot being used on my server https://i.redd.it/m1ure9744gv81.gif If you are interested feel free to add the bot to your server with this link: [https://discord.com/api/oauth2/authorize?client\_id=964251008115019847&permissions=116736&scope=bot](https://discord.com/api/oauth2/authorize?client_id=964251008115019847&permissions=116736&scope=bot) Also DM me (ScriptLine Studios#8597) if you need help or run into issues!

Pons, an async Ethereum RPC client library

I've been waiting a long time for async support in `web3`, and now that it started to appear, it only supports `asyncio` (while I use `trio` in my application), and is in general not quite finished. So I decided to write an RPC client of my own with convenient contract calls, simple structure (instead of a hundred levels of indirection in `web3`) and strictly typed. Still a lot of possible enhancements possible, but it is already useful (well, I use it, at least :). Repo: https://github.com/fjarri/pons A simple example: import trio from eth_account import Account from pons import Client, HTTPProvider, AccountSigner, Address, Amount async def main(): provider = HTTPProvider("<your provider's https endpoint>") client = Client(provider) acc = Account.from_key("0x<your secret key>") signer = AccountSigner(acc) async with client.session() as session: my_balance = await session.eth_get_balance(signer.address) print(my_balance) another_address = Address.from_hex("0x<some address>") await session.transfer(signer, another_address, Amount.ether(1.5)) my_balance = await session.eth_get_balance(signer.address) print(my_balance) trio.run(main) More in the [Tutorial](https://pons.readthedocs.io/en/latest/tutorial.html#tutorial) (not very extensive for now, but hopefully gives an idea of how to use it), and of course there's always the [API reference](https://pons.readthedocs.io/en/latest/api.html). I am sure there are a lot of usage scenarios I haven't even considered, so I would be especially grateful for complaints about this or that method/parameters/naming being inconvenient, counterintuitive, confusing, or out of place.

Deciding what to use among Cython / Pypy / Numba

So I want to experiment and speed up my code. I have studied the basics of Cython and Numba but Pypy only has 10 year onld videos. What I have found: - Cython converts Python into C and makes the code useable in both Python and C - Numba directly converts Python into Machine code and is useful for Math operations (numpy) - Numba is JIT compiler - Both Cython and Numba don't support 3rd party libraries like Pandas and spacy.. - Pypy is an implementation of Python. Normally the Python we use when we write python abc.exe in cmd is Cpython(not Cython). - Numba and Cython speed up the code a lot if the code is compatible... things like list don't work with Numba... Would be super helpful if someone can please explain the difference between Numba, Cython and Pypy and when to use which. Even pointing me to the resources would be great! Thanks in advance.

A simple python library that can be used to run large Web3 queries on Ethereum blockchain concurrently as per Ethereum JSON-RPC specification.

A simple python library that can be used to run large Web3 queries on Ethereum blockchain concurrently as per Ethereum JSON-RPC specification. The library provides a bare minimal framework for expressing raw JSON-RPC queries as described in the Ethereum Specification and execute them together either concurrently (off-chain on the client side) or together as a batch (JSON-RPC batch specification on-chain). This method greatly reduces the time required to run large queries sequentially and thus can be used for use-cases where we need to index large number of transactions happening on ethereum blockchain in a local database for faster Web2 queries.

I created a simple two-step parking space counter: \- first, you mark the positions of all parking spaces you are interested in using "parking\_space\_picker.py"; \- second, you run "parking\_space\_counter.py" to check if the parking space is vacant or not and count them. [RESULT](https://youtu.be/LERHWFmSSdM) [CODE](https://github.com/codegiovanni/Parking_space_counter) ​ Video used in the code: Tom Berrigan [https://www.youtube.com/watch?v=yojapmOkIfg&list=LL&index=10](https://www.youtube.com/watch?v=yojapmOkIfg&list=LL&index=10) ​ The code is inspired by: Murtaza's Workshop - Robotics and AI [https://www.youtube.com/watch?v=caKnQlCMIYI](https://www.youtube.com/watch?v=caKnQlCMIYI)

Space Science: Autoencoder latent space visualization of asteroid spectra

Hey Everyone, Last time, I introduced Autoencoders (using Keras) to develop a deep learning architecture that learns a low-dimensional representation of asteroid reflectance spectra. Although I compressed the 49-dimensional spectra to only 2 dimensions, the results were quite fair. So... why did I compress it so ridiculously high? Well, a 2-D space can easily be visualized! And this visualization is being done today. In today's tutorial, we'll use Matplotlib for a static display of the data, and ipwidgets, to create an interactive widget within our notebook on Google Colab! Let's see whether our 25-fold compression leads to some proper latent space, where the asteroid classes can be distinguished: GitHub Link: [https://github.com/ThomasAlbin/Astroniz-YT-Tutorials/blob/main/%5BML1%5D-Asteroid-Spectra/12\_dl\_autoencoder\_latent\_space.ipynb](https://github.com/ThomasAlbin/Astroniz-YT-Tutorials/blob/main/%5BML1%5D-Asteroid-Spectra/12_dl_autoencoder_latent_space.ipynb) YouTube Link: [https://www.youtube.com/watch?v=h26O2qbc5DA](https://www.youtube.com/watch?v=h26O2qbc5DA) The next session will be the final one of the asteroid science project. There, we will create a higher dimensional latent space and apply some clustering algorithm to determine the number of asteroid classes from a data-scientific perspective. Stay tuned! Thomas

How do you manage conflicting packages in your requirements.txt ?

Hi, Let's say you have in your requirements.txt : package_A package_B package_C package_D but `package_A` requires `some_dependency<=1.5` and `package_B` requires `some_dependency>=2.2` . How do you handle that (knowing that I might have tens of conflicting packages)? I don't think virtualenvs would be a good solution here since the project has one entry point and packages are imported in the same code ... Thank you !:)

"Community is essential to programmers" - Eric Matthes

I've just started working my way through Eric Matthes' Python Crash Course. In his introduction he states, " Community is essential to programers because programming isn't a solitary pursuit.... Having a well connected community is critical in helping you solve problems, and the Python community is fully supportive of people like you who are learning python as your first programming language." ​ I've dabbled a bit in the basic front end languages and I'm currently playing around with Vue so I wouldn't say it's my first language. However, I did feel compelled to reach out to this community after reading that. If you have any advice for someone starting to pick up python, I'm happy to listen and learn.

I’m going to learn python over the summer, but coming from Java & c# in IDE’s where casting etc can auto completed within the problem pane when making newb mistakes, and also knowing the pain of PHP runtime errors, I’m hoping the dynamic experience will be smoother with python. I’m ranting.. would this be feasible ? Just a thought.

Car Wash Pattern: Parallelizing Non-Thread Safe and/or CPU-intensive Processes with Future Based Queue Centric Approach in Python

This article can be a useful guide for parallelizing non-thread-safe and CPU-bound processes, such as some machine learning models, for purposes such as model to web service conversion. While developing the solution, I tried to pay particular attention to the advantages, disadvantages and pitfalls of python. Maybe there is nothing new for the masters, but I think it is a neat resource for the enthusiasts.

Searching a student apartment in Zürich was too boring so I made a Telegram bot.

[GitHub link](https://github.com/bskdany/WokoWGZScraperBot) Basically anyone I know checks every day [woko.ch](https://woko.ch) and [wgzimmer.ch](https://wgzimmer.ch) for rooms and apartments that are being rented for students in Switzerland , the first to contact the seller usually gets the room. I don't have the time and will to do that. So I made a bot that scrapes both those websites with requests and BeautifulSoup. The bot collects the urls of the rented rooms and saves them in a txt, then it checks the website every minute for changes. If a new url is found then the room data is sent to me with the Telegram API. Both those websites don't have a policy against scraping, but they do have some little bot protection. Yeah that's it, I made this in two days and I'm hosting the bot on heroku. Suggestions are welcome (especially in security).

Unpopular opinion: Matplotlib is a bad library

I work with data using Python a lot. Sometimes, I need to do some visualizations. Sadly, matplotlib is the de-facto standard for visualization. The API of this library is a pain in the ass to work with. I know there are things like Seaborn which make the experience less shitty, but that's only a partial solution and isn't always easily available. Historically, it was built to imitate then-popular Matlab. But I don't like Matlab either and consider it's API and plotting capabilities very inferior to e.g. Wolfram Mathematica. Plus trying to port the already awkward Matlab API to Python made the whole thing double awkward, the whole library overall does not feel very Pythonic. Please give a me better plotting libary that works seemlessly with Jupyter!

Hey guys, I just learned Django and React, I know my few things about python amd javascript. Ive done small projects using "Django Rest Framework". My question is, can I build an API from scratch without using Django or DjangoRest Framework? Im curious how its done. All the google searches Ive done they give back answers usimg Django or flask. If I had only python, postgres, javascript, html and css to work on...how can I build an API without frameworks? The idea of creating one from scratch confuses me since Ive only built one using Django Rest Framework. Any guidance will help.
