In Python, comments are denoted by the pound sign (#). Anything following a pound sign on the same line is ignored by the interpreter.
For example, the following is a single-line comment:
# This is a single-line comment
Multi-line comments can be created by using triple quotes, either single or double.
""" This is a multi-line comment """
''' This is a multi-line comment '''
It is a good practice to include comments in your code to explain what the code does, how it works, and why it's necessary. This makes your code more readable and easier to understand for others (or yourself) who may need to modify or debug it in the future.
