Python Comment: A Beginner Guide to Python Comment

This article will explore the significance of comments in Python programming. We will highlight how comments can clarify the purpose and logic of code and contribute to generating comprehensive documentation. We also covered the two types of comments in Python: single-line and multiline comments, along with examples of their usage.

Table of Contents


In Python programming, comments are crucial in enhancing code readability and providing additional information about the code to developers and future readers. Comments are lines of text not executed by the Python interpreter and are solely meant for human readers to understand the code’s purpose, functionality, or any other relevant details.


Comment in Python is used with # Symbol. If any line starts with # Symbol is considered a Comment and ignored by the Python interpreter.

Write a Comment

					#Hello World
#This is a Comment.

Since, it is Comment, Python will not print anything.

For a better understanding of code, we can write comments at the end of the line, too, but they can not be considered Comments in Python.

					print("Hello") # It will not stop Python from executing code.
print("World") # It will not stop Python from executing code.
print('This is not a Comment.') # It will not stop Python from executing code.
This is not a Comment.

Multiline Comment

Multiline Comment refers to Comments in more than one line. 

Python allows us three ways to write multiline Comments –

  1. using # Symbol at the beginning of each line; 
  2. write lines between single-triple quotes ”’
  3. write lines between double-triple quotes “””

Multiline Comment using # Symbol

					#This is a multiline Comment using # Symbol.
#This is also a multiline Comment using # Symbol.

Since, it is Comment, Python will not print anything.

Multiline Comments using single-triple quotes

This is a
multiline Comment using single-triple quotes in Python.


Multiline Comment using double-triple quotes

This is a
multiline Comment using double-triple quotes in Python.

print("This is not a multi-line Comment.")
This is not a multi-line Comment.

Advantages of Comment in Python

  1. Code Explanation: Comments can be used as code explanations for a better understanding of code. This helps us to understand code structure more easily and make complex code more comprehensive.

  2. Documentation: Comments can be easily used as notes, information, or rough documentation to remember the code implementation and help to understand the code for others.

  3. Debugging:  Comments can temporarily disable certain lines of code during debugging. By commenting out specific lines, you can narrow down the source of an issue.

Disadvantage of Comment

  1. Using frequent Comments can make code clearer to understand.
  2. Sometimes Comments can make code dirty; if used more than needed.
  3. Over-commenting or leaving unclear comments can make the code harder to read and maintain.

Note:  Remember that comments should be concise, clear, and relevant. It’s important to strike a balance and provide meaningful comments that add value to the codebase. By utilizing comments effectively, we can enhance collaboration, maintainability, and understanding of your Python code.


Python comments are a vital aspect of coding that greatly contribute to the readability, understanding, and maintainability of Python code. Using comments appropriately allows developers to provide valuable explanations, document their code, and facilitate collaboration among team members.

It’s important to note that while comments are beneficial, it’s crucial to strike a balance. Over-commenting can lead to cluttered code, while insufficient or unclear comments may hinder understanding. However, using comments as a powerful tool in your coding arsenal will ultimately result in more efficient and robust Python applications.
