Python comments are a great way to provide context and notes for your code. They are beneficial when you are working on a large project and need to keep track of what is happening in different parts of your code.
This article will show you how to create and use comments in Python and give tips for getting the most out of them. Ready to start commenting on your code? Let us get started.

What are Comments in Python Programs?
Comments are one of the many features that make online programs unique and engaging. For example, they allow users to provide feedback, suggestions, or comments about the content or functionalities of a program. Comments help to improve the user experience by providing an avenue for communication between program creators and their customers.
Python Comments: Advantages
Comments play an important role in programming and are essential instructions left for other programmers to read. They can help you to clarify the code or provide additional information about what you are doing. Additionally, comments can be used to document your code so that others may understand it better. Comments are constructive when debugging programs as they allow you more insight into how the code works and where errors might be lurking.
Types of Comments in Python
Comments are a great way to provide feedback and suggestions on code or text. For example, they can be used for anything from documenting your code to providing explanations of algorithms or modifiers. Python has support for both single-line and multi-line comments, which means you can use them in various ways. You can also include references to external files in your comments, making sharing data between different program modules easy.
Single-Line Comment
In Python, the “#” symbol indicates a single-line comment. This comment allows you to include comments in your code without typing out long lines of text. Place the # symbol at the beginning of a line and hit ENTER; everything from that point onwards will be considered part of the comment.
# Print “welcome to codeleaks” to console
print("welcome to codeleaks")
Output
Multi-Line Comment
The multi-line comment in Python is a type of declaration that allows multiple lines of code to appear as one statement. This can be helpful when you want to include long blocks of code without breaking them into individual statements. Additionally, this style makes the code more readable and easier to understand.
# Print “welcome to codeleaks” to console
# python program to print multiline comments
print("welcome to codeleaks") Output
Python String Literals
String literals are a way of writing strings in Python that allows you to place multiple lines of text within a single string. This can be useful when you want to include comments or other explanatory text along with your code.
"""Print welcome to codeleaks to console
python program to print multiline comments"""
print("welcome to codeleaks") Output
Python Docstring
Python docstring is a method that allows you to include documentation for your classes, functions, and variables in the source code.it is the string literal with triple quotes This makes it easy for other developers who might need to reference or use your code later.
def divide(a, b):
"""divided value of a and b"""
return a/b
# Print the docstring of multiply function
print(divide.__doc__) Output

FAQs
Can comments be nested?
Python does not support nesting multiline comments. The only safe option is to comment out each line if you want to comment out numerous lines allowing for nested comments.
Can too many comments slow down your code?
In most situations, commenting will not affect the script’s execution time. Instead, the parser is greatly affected by the number of lines written in your code.
Do comments increase compile time?
The compiler has to read more text because each comment you write will make the compilation slower.
Conclusion
As you can see, comments are not just a vital part of your programs. They also provide an avenue for communication between you and the users that help in improving their experience with your content. We hope this article has helped you understand the importance of Python comments and how to create them effectively. Thanks for reading.
