docopt in python is giving me issues -


i have set of 3 programs trying combine one. work individually, having issues when trying them work together. issue having first section of code:

import os import sys contextlib import closing  import colorama  # $ pip install colorama import docopt  # $ pip install docopt import socks  # $ pip install pysocks import stem.process  # $ pip install stem sockshandler import socksipyhandler  # see pysocks repository stem.util import term  try:     import urllib2 except importerror: # python 3     import urllib.request urllib2  args = docopt.docopt(__doc__, version='0.2') colorama.init(strip=not (sys.stdout.isatty() or args['--color'])) 

when run program, error:

traceback (most recent call last):   file "cilantro.py", line 34, in <module>     args = docopt.docopt(__doc__, version='0.2')   file "c:\python34\lib\site-packages\docopt.py", line 558, in docopt     docoptexit.usage = printable_usage(doc)   file "c:\python34\lib\site-packages\docopt.py", line 468, in printable_usage     raise docoptlanguageerror('"usage:" (case-insensitive) not found.') docopt.docoptlanguageerror: "usage:" (case-insensitive) not found. 

why getting error message? same code works fine in original program.

when using docopt need write __doc__ string script. docopt parses string work out how handle command line options , arguments.

to fix this, , following text above "import os" (so it's first thing in file):

""" name. describe script  usage:  name <firstarg>  name --countdown  name sillycommand <sillyness>  name -h | --help  options:   --countdown  display count down """ 

more details on put in usage string can found @ docopt documentation, http://docopt.org/
