Python Comments

This lesson is part of Python · All levels

Summary

Comment is a note that is not executed by an interpreter and is useful for explaining the content of the code. In Python, one-line comments are written with the # sign, while a string docstring triple quote can be used as a function or module documentation. Proper commenting makes code easier for teams to understand without changing program behavior.

Key points

The # sign starts with a one-line comment that the interpreter passes.
Multi-line comments can be written with a three-quotation mark.
Docstrings are often used to document functions or modules.
The comment explains why a code was written, not the repetition of the code itself.
