In this tutorial, we describe how, when and why to use comments in Python. We cover Single-line, Multi-line, and Docstring comments.
In simple terms, a comment is an entry added to the source code to allow a deeper understanding of the logic behind why the code was written the way it was. In Python, the ‘#’ or pound symbol is required before every comment. This symbol allows the Python interpreter or compiler to ignore the pursuant text.
When working in a large codebase, a developer may need to refer back to the information in comments weeks or months later to ensure that they understand the code’s original purpose. This information is necessary for the original idea’s formal logic aspect and is an essential criterion when working with other developers on an extensive project.
Developers who review and/or follow up to revise a code section often rely heavily on the comments to recognize and follow the original developer’s thought processes. In this way, successive developers can add, edit, or modify the annotation to adjust the understanding or reasoning of further updates if the code changes.
The default Python library requires lines of code to be no longer than 79 characters. This provision is different for comments, which is 72 characters. If a comment stretches beyond the 72 character docstring limit, the dev should add a second line beginning with the ‘#’ symbol. More than one line is often needed to explain the reasoning behind how or why a developer wrote the code.
When a comment is added, it should be written in complete sentences. It should also concisely express a simple idea to limit the explanation’s focus only to the section of code requiring clarification.
Typically, a dev should capitalize the first word of a comment. If it is used as an identifier, the initial term should begin with a lowercase letter.
In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.
Today you're going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates. We gonna use Python OS remove( ) method to remove the duplicates on our drive. Well, that's simple you just call remove ( ) with a parameter of the name of the file you wanna remove done.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc.. You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like __init__, __call__, __str__ etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).
The OS module is a python module that provides the interface for interacting with the underlying operating system that Python is running.
