I\'m using argparse in Python2.7 and I would like to display multiple lines in the help text of an argument.

My codes look like this:

import argparse

         


        

Answer 1

The simplest thing you could do would be to place the lines in an array and then join them with newlines like so:

help_lines = ['First line', 'Second line', '', 'More lines']
# ...
parser.add_argument('--argument', default=None, type=sometype,
help='\n'.join(help_lines))
