What is a feature of Python you wish you knew earlier?

In this article, we will introduce a few secret features of Python that you may not have known before.

Here are some hidden Python features we must know about -

Pandas_ml

Pandas is one of the most famous Python machine learning libraries. This library is intended for data analysis and manipulation. Additionally, it's useful because it combines some of Python's greatest and most trusted libraries into one package. Therefore, its use and application are simple.

Parameter unpacking

List unpacking fails when used in functions; Python itself does not unpack lists or tuples when passed to functions. This is due to possible ambiguity: it is up to the developer to indicate when this must be done.

Slice allocation

Suppose you have a list. But you must replace multiple items in the list with a single assignment. what will you do? This is where slice allocation comes in handy. Python allows you to replace part of a list with whatever you want with just one line.

List comprehensions in Python

List comprehension is one of Python’s most powerful techniques. It helps to derive one list from another by using concise syntax. List comprehensions come in handy when you want to filter items in a list or apply a function to them. Therefore, it is one of the most important hidden Python features.

Use black formatting code

What if you could review code faster and more efficiently? This is where the Python code formatter Black comes into play. One of Python's best unknowns is formatting, which allows you to create code the way you like. Black formats it, speeding up the entire code review process.

Python Debugger

We got into some bugs and spent a long time trying to fix them. Moreover, all our efforts will be in vain. The solution is unknown, but our efforts are in vain. This is when you have to use a Python debugger to simplify your task.

Python Debugger Allows you to easily inspect your code line by line. Therefore, it is one of the greatest features of Python.

Using emoticons in code

Did you know that Python provides a module that allows you to add emojis to strings? Yes, you are not mistaken! To include emoticons, you can use the Emoji module or Unicode.

Import data science library

We often spend a lot of time importing common libraries, such as seaborn or pandas. And importing them manually can be very time-consuming.

So there is a solution in the form of the pyforest library that can help you overcome this challenge. This module is a bonus and one of Python's hidden features. Direct operation is more convenient than importing separately.

Negative index

Negative indexing is one of Python’s hidden features. We all know that indexing is used in arrays in all programming languages. These indices are then used to access the items of the array.

However, all programming languages ​​limit the use of negative indexes, such as "-2". However, Python is an exception as it supports negative array indexing. Therefore, -1 should be the last element and -2 should be the second to last element.

Chain comparison operator

Many computer languages ​​make it easy to use syntax to compare values. for example -

A > B and A > D

Wouldn't it be amazing if the "and" operator was removed from the syntax? Fortunately, Python allows you to use comparison operators one after the other, as shown below.

A > B > C

This is due to "Operator Preference and Relevance". It is used in expressions and is useful when there are multiple operators with different precedence. Additionally, assist in determining which procedure should be performed first.

Easily swap variables

Python helps make difficult jobs easier. For example, suppose you have two variables and need to swap their values. So what will you do? Manually create a temporary variable when exchanging other values. There are no flaws in this approach, but some may find it tedious. In contrast, Python facilitates swapping without the use of temporary variables.

Example

# intializing two variables
x = 20
y = 50

# swapping the values of x, y variables
x, y = y, x

# printing x, y values after swapping
print("x value after swapping:", x)
print("y value after swapping:", y)

Output

x value after swapping: 50
y value after swapping: 20

In this case, Python deletes the temporary variable in the background after the operation is completed. Therefore, it helps in creating efficient and clear code.

Short module name

Are you tired of repeating long library names? Then the following hack will undoubtedly be of benefit to you. Python allows developers to create any library name they want using the keyword "as".

Easter Egg List

Some people may find programming as tedious as writing argumentative essays and other academic tasks. But what if we say Python contains Easter eggs? This may seem strange, since Easter eggs are commonly found in video games, movies, cartoons, and other media.

Start the network server

Python's hidden features are just as useful as website support. Consider the following scenario: You want to set up your own web server to exchange files from your computer.

一个简单的命令对此很有用。它将在任何可用端口上启动 Web 服务器。为了确保一切顺利，请将端口号从 0 更改为 65353。您可以探索更多参数。

# Running Web Server
python -m http.server 7000

结论

无论您是 Python 新手还是专家，这种语言仍然能让您感到惊讶。有许多您不知道的 Python 功能。

这些功能不仅对开发人员有用，而且也易于理解。因此，如果您认为自己了解有关 Python 的所有知识，请阅读本文并了解有关最流行的编程语言之一的新知识。
