I checked the help format. the help_lines' width in python2.7 is different python3. The width is more likely a hardcode in https://github.com/python/cpython/blob/2.7/Lib/argparse.py#L165. , so the help_lines = [u'This is a very long help string. ex: "--s3', u's3://my.bucket/dir1/dir2"'](when joining this help_lines it will add a '\n' in the middle) Since python 3.3, the width is a dynamic value in https://github.com/python/cpython/blob/master/Lib/argparse.py#L170 , so the help_lines = ['This is a very long help string. ex: "--s3\xa0s3://my.bucket/dir1/dir2"']
