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.
Comments starts with a #, and Python will ignore them: #This is a comment
Python does not have multiline comments.
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 over
multiple lines
"""
