05 How to write comments in Python?

0
41

Like other programming languages Python also has commenting capability for the purpose of in-code documentation.

Single Line Comment:

Comments start with a #, and Python will render the rest of the line as a comment: 

Example:

#This is a comment.
print("Hello, World!")

Or

print("Hello, World!") #This is a comment

Multy-Line Comment:

In-fact Python does not have any syntax for multi-line comments. To add a multiline comment you could insert a # for each line:

Example:

#This is a comment
#written in
#more than just one line
print("Hello, World!")

Or, you can also use a multiline string for multi-line comment.

Python ignores string literals that are not assigned to a variable, you can add a multiline string (triple quotes) in your code, and place your comment inside it.

Example:

"""
This is a comment
written in
more than just one line
"
""
print("Hello, World!")

As long as the string is not assigned to a variable, Python will read the code, but then ignore it, and you have made a multiline comment.
