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/

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
