Python Comments
Comments can be used to prevent execution when testing code.
Creating a Comment
Comments start with a #, and Python will ignore them:
Example
#This is a comment
print("Hello, World!")Try it Yourself »Comments can be placed at the end of a line, and Python will ignore the rest of the line:
Example
print("Hello, World!") #This is a commentTry it Yourself »A comment does not have to be text that explains the code, it can also be used to prevent Python from executing code:
Example
#print("Hello, World!")
print("Cheers, Mate!")Try it Yourself »Multi-Line Comments
Python does not really have a 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!")Try it Yourself »Or, not quite as intended, you can use a multiline string.
Since Python will ignore 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!")Try it Yourself »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.
