We use Python comments to explain or clarify the code. The interpreter ignores them and does not run them as part of the program.
Python Comments are denoted using the pound sign (
#
). Everything after the
#
on a given line is considered a comment and is ignored by the interpreter.
Here’s an example:
1 2 | # This is a comment print("Hello, World!") # This is also a comment |
Multi-line comments can be created using triple quotes (
'''
or
"""
). Anything between triple quotes is considered a comment and is ignored by the interpreter.
Here’s an example:
1 2 3 4 5 | ''' This is a multi-line comment. It can span multiple lines. ''' print("Hello, World!") |
Comments are useful for documenting code and explaining what it does. You can also use them to temporarily disable pieces of code (by commenting them out) without deleting them.
Some of the important points regarding the Python comment:
- In general, it is a good idea to use comments in your code to explain what you are doing, especially if your code is not self-explanatory. This can help you and others understand the code more easily and make it easier to maintain.
- It is also a good idea to use comments to document the purpose of a function, class, or module. This can help others understand what the code is intended to do and how to use it.
- Comments should be used to explain the overall logic of the code and not to explain every single line. The code itself should be self-explanatory and easy to understand.
- Avoid using comments to repeat what the code is doing. If you find that you need to use comments to explain what the code is doing, it may be a sign that the code is not written in a clear and concise manner and may need to be refactored.
- It is generally a good idea to use multi-line comments for longer explanations and single-line comments for brief explanations or clarifications.
- In Python, the
#
symbol is used to denote a single-line comment. Everything after the#
on a given line is ignored by the interpreter and is not executed as part of the program. - To create a multi-line comment, you can use triple quotes (
'''
or"""
). Anything between triple quotes is considered a comment and is ignored by the interpreter. - It is generally a good idea to use comments to explain the overall logic of your code and not to explain every single line. The code itself should be self-explanatory and easy to understand.

- It is also a good idea to use comments to document the purpose of a function, class, or module. This can help others understand what the code is intended to do and how to use it.
- When writing comments, it is important to use clear and concise language. Avoid using jargon or abbreviations that may not be familiar to others reading the code.
- Finally, it is a good idea to use comments sparingly. Overly commented code can be hard to read and maintain.
