[Python](https://www.python.org/) is known for making it easy to write beautiful, small code. Today’s pro tip is about how to get the last element of a list using this language \o/

Coming from other languages like Java or C to Python, it’s normal to bring a bit of an accent to your codes and want to do something more or less like this to get the last element of a list:

```
my_list = [1, 2, 3, 4, 5]
item_index = len(my_list) - 1
print(item_index)
# 4
last_one = my_list[item_index]
print(last_one)
# 5

```

Use the `len()` size function to get the length of the list and subtract `1` to get the index of the last element in that list. And that’s ok! It works. However, Python presents a more elegant way of doing this, see:

```
last_one = my_list[-1]
print(last_one)
# 5

```

![magic gif](https://media.giphy.com/media/12NUbkX6p4xOO4/giphy.gif)

Even though it may seem like this, it’s not magic! From the [Python documentation](https://docs.python.org/3/library/stdtypes.html#common-sequence-operations):

> If i or j is negative, the index is relative to the end of sequence _s_: `len(s) + i` or `len(s) + j` is substituted. But note that `-0` is still `0`.

In a simpler way, [Raymond Hettinger](https://twitter.com/raymondh) explains in this tweet with code:

<center>
<blockquote data-lang="pt">
<p lang="en" dir="ltr"><a href="https://twitter.com/hashtag/python?src=hash&amp;ref_src=twsrc%5Etfw">#python</a> tip: How to support negative indexing:<br><br>def __getitem__ (self, i):<br> if i &lt; 0:<br> i += len(self)<br> if i &lt; 0 or i &gt;= len(self):<br> raise IndexError<br> ...</p>— Raymond Hettinger (@raymondh) <a href="https://twitter.com/raymondh/status/943615980650971136?ref_src=twsrc%5Etfw">20 de dezembro de 2017</a>
</blockquote>
<script async="" src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
</center>

The implementation is actually more complex than this, but what happens in general terms: the ` __getitem__ ` method is invoked when we call `my_list[-1]` receiving the list itself (`self`) and the negative index (`i`) then adds this index with the size of the list and returns the updated index value. Interestingly, this was the same thing I did on the first example but it is already implemented by default.

And a little detail, the same can be done for strings!

```
word = 'yes'
print(word[-1])
# s

```

Dope, right? Now just use negative index in your codes too 😉

SOLID Principles: Interface Segregation Principle (ISP)
Tags: solidprinciples, designpatterns, interfacesegregation, architecture
Published: 2023-09-11 09:01:01

## 🪨 SOLID Principles

[**SOLID**](https://dev.to/amburi/solid-principles-3jpo) is a list of 5 software engineering principles. It is a meta acronym where each letter corresponds to another acronym:

- [SRP: Single Responsibility Principle](https://dev.to/amburi/solid-principles-single-responsibility-principle-srp-4bfm)
- [OCP: Open-Closed Principle](https://dev.to/amburi/solid-principal-open-closed-principle-ocp-doe)
- [LSP: Liskov Substitution Principle](https://dev.to/amburi/solid-principles-liskov-substitution-principle-lsp-1pco)
- **ISP: Interface Segregation Principle**
- [DIP: Dependency Inversion Principle](https://dev.to/amburi/solid-principles-dependency-inversion-principle-dip-1cpk)

Without any further ado, let's jump into today's topic:

## Interface Segregation Principle (ISP)

Interface Segregation Principle (ISP) is one of the SOLID principles of object-oriented programming. 

An interface should have a specific, well-defined purpose, and clients should only be required to implement the methods that are relevant to their needs. Clients should not be forced to depend on interfaces they do not use. 

**Goal:** The aim is to make software design more modular and flexible by avoiding the creation of large, monolithic interfaces that compel clients to implement unnecessary methods.

- Encourage the use of smaller, client-specific interfaces.
- Decreases coupling by preventing clients from relying on unnecessary methods, which, in turn, reduces the connection between classes and interfaces.
- Enhances modularity by designing smaller, focused interfaces that make it easier to understand and maintain the code.
- Improves reusability as clients can implement only the interfaces and methods relevant to their specific context, thus promoting code reusability.
- Simplifies testing through narrowly-focused interfaces, allowing clients to test only the methods directly associated with their functionality.

### Bad Example:

```php
interface Worker {
    public function work();
    public function eat();
}
```

Here, we have a single interface, `Worker`, that includes two methods: `work` and `eat`. If a class needs to implement this interface but doesn't require both methods, it will be forced to provide empty implementations or methods with no meaningful behavior, violating the ISP.

### Good Example:

```php
interface Workable {
    public function work();
}

interface Eatable {
    public function eat();
}
```

Here, we've segregated the original `Worker` interface into two smaller, focused interfaces: `Workable` and `Eatable`. Now, classes can choose to implement one or both interfaces based on their specific needs. This adheres to the Interface Segregation Principle, promoting better code design and flexibility.

The SQL Language (Part-4)
Published: 2023-09-11 08:30:52

## Aggregate Functions:

PostgreSQL Supports aggregate functions, It computes single result from multiple input rows. 
Aggregates to compute:
- `Count`
- `Sum`
- `avg`(average)
- `max`(maximum)
- `min`(minimum)
over the set of rows.

It is important to understand the interaction between aggregates and SQL's WHERE and HAVING clauses.
The fundamental difference between WHERE and HAVING is this: WHERE selects input rows before groups
and aggregates are computed (thus, it controls which rows go into the aggregate computation), whereas
HAVING selects group rows after groups and aggregates are computed. Thus, the WHERE clause must not
contain aggregate functions; it makes no sense to try to use an aggregate to determine which rows will
be inputs to the aggregates. On the other hand, the HAVING clause always contains aggregate functions.
(Strictly speaking, you are allowed to write a HAVING clause that doesn't use aggregates, but it's seldom
useful. The same condition could be used more efficiently at the WHERE stage.)

## Updates
You can update existing rows using the UPDATE command. Suppose you discover the temperature readings are all off by 2 degrees after November 28. You can correct the data as follows:
UPDATE weather
 `SET temp_hi = temp_hi - 2, temp_lo = temp_lo - 2
 WHERE date > '1994-11-28';`

## Deletions
Rows can be removed from the table using `Delete` command.
If you no longer want any query to execute you can use `Delete` command:
`DELETE FROM weather WHERE city = 'Hayward';`

Top Four Challenges in Test Automation
Published: 2023-09-11 08:17:53

Automation testing is a testing technique to test and compare the actual outcome with the expected outcome. It is an essential subset of software testing. However, there are many challenges in applying test automation for applications under test. Here are some of the most common challenges you should consider to mitigate the risks of test automation failures.

**Challenge 1: High upfront investment cost**
Automation increases testing velocity but the cost can be a major concern. The initial phase of implementing automation is always expensive. It is important to analyze, design, and build the test automation framework, reusable functions, libraries, etc. Certain cases may involve licensing costs except for the usual operational costs. One must also take into account the cost incurred in training the resources and setting up the grid.

**Challenge 2: Finding the right tool**
Finding the right automation tool is a very crucial challenge. There are many tools available now, the choice of tool depends on the kind of application and the extent of automation testing. Before selecting a particular tool, the test engineer should evaluate the pros and cons of each tool and consider based on the basis of the some points such as scalability and maintainability.

**Challenge 3: Ensuring Adequate Test Automation Coverage**
Another major challenge in automation testing is a lack of infrastructure to enable proper test coverage and execution speed. When testing applications against multiple browsers and operating system combinations, test scripts must run in parallel to run each test against the configuration in a reasonable amount of time. The infrastructure must support the parallelization strategy.

**Challenge 4: Effective Communicating and Collaborating in Team**
Automation testing is more complicated than manual testing because it requires more communication and collaboration .The team need to spend efforts on communication and provide huge evidence, historical data, and even do a proof of concept. Ineffective communication and collaboration can quickly turn test automation experiences into nightmares.

## Summary
These challenges are not the only ones found in test automation, yet they are common. If we don't have solutions to overcome them, it can easily result in failure. So we will also provide detailed solutions in the following articles, please stay tuned!

[RT-PCR](https://www.creative-biogene.com/support/rt-pcr-protocol.html) (reverse transcription-polymerase chain reaction) is a variant of the polymerase chain reaction (PCR) which are now widely used. Traditionally RT-PCR involves two steps: the RT reaction and PCR amplification. RNA is first reverse transcribed into cDNA using a reverse transcriptase as described here, the resulting cDNA is used as templates for subsequent PCR amplification using primers specific for one or more genes. RT-PCR can be used to quantify mRNA levels from much smaller samples. In fact, this technique is sensitive enough to enable quantitation of RNA from a single cell.
Reporter Stable Cell Lines
Published: 2023-09-11 08:08:11

As useful tools for scientific research, [reporter stable cell lines](https://www.creative-biogene.com/products/reporter-stable-cell-lines.html) are those cells involved in expression of reporter protein(s) which are engineered through integrating the reporter expression cassettes into cell genomes mediated by plasmid or lentivirus vectors. In the studies of life science and biotechnology, the commonly used reporter genes are visually identifiable including green fluorescent protein (GFP), red fluorescent protein (RFP), luciferase, secreted alkaline phosphatase (SEAP) etc.
