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.
Creating a Comment
Comments starts with a
#, and Python will
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:
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:
#more than just one line
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
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.
