How to Comment in Python Code?

Estimated read time 2 min read

In Python, you can add comments to your code to provide explanations, document your code, or temporarily disable specific lines of code. Comments are ignored by the Python interpreter and are not executed as part of the program.

There are two ways to add comments in Python:

  1. Single-line comments: To add a comment that spans only one line, you can use the hash symbol (#) at the beginning of the line. Everything after the hash symbol on that line will be treated as a comment. Here’s an example:
# This is a single-line comment
print("Hello, world!")  # This is another comment

In the above example, both lines starting with a hash symbol are comments and will not be executed.

  1. Multi-line comments: If you want to add comments that span multiple lines, you can enclose them between triple quotes (”’ ”’) or triple double quotes (“”” “””). This is also known as a docstring, and it’s commonly used to provide documentation for functions, classes, or modules. Here’s an example:
"""
This is a multi-line comment or docstring.
You can write as many lines as you want.
"""

print("Hello, world!")

In this case, the lines enclosed between the triple quotes are comments and will not be executed.

It’s important to note that comments are useful for code readability and maintainability. It’s a good practice to include comments to explain complex logic, assumptions, or any other relevant information that can help others (including yourself) understand the code in the future.
