Python Comments

Comments can be used to explain Python code. Comments can be used to make the code more readable. Comments can be used to prevent execution when testing code.

#, and Python will ignore them:

Comments can be placed at the end of a line, and Python will ignore the rest of the line:

A comment does not have to be text that explains the code, it can also be used to prevent Python from executing code:

Python does not really have a syntax for multiline comments. To add a multiline comment you could insert a # for each line:

#This is a comment #written in

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:

""" This is a comment written in more than just one line """

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.
