How to Create Multiline Comments in Python

Using triple-quoted Strings

String literals can span multiple lines. One way is using triple-quotes: """...""" or '''...'''.

You can use triple-quoted strings. When they're not a docstring, they are ignored.

See the following example:

#!/usr/bin/python3

'''
This is a multiline
comment.
'''

""""
This is a multiline
comment.
"""

def parses(token):
  """
  This function parses a token.
  TODO: write a decent docstring :-)
  """
  pass

Make sure to indent the leading ''' appropriately to avoid an IndentationError.

Using Consecutive Single-Line Comments

Python's style guide, PEP8, favors using consecutive single-line comments, like this:

#!/usr/bin/python3

# This is a multiline
# comment.

Python Errors

IndentationError: unexpected indent

#!/usr/bin/python3
 '''...

 '''
IndentationError: unexpected indent
