Return to Python Topics, Comments or Python Lessons

Comments starts with a #, and Python will ignore them:

1. This is a comment

print(“Hello, World!”) Comments can be placed at the end of a line, and Python will ignore the rest of the line:

print(“Hello, World!”) #This is a comment Comments does not have to be text to explain the code, it can also be used to prevent Python from executing code:

1. print(“Hello, World!”)

print(“Cheers, Mate!”) 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:

1. This is a comment
2. written in
3. more than just one line

print(“Hello, World!”) 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 ”“” 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.
