docopt not printing arguments

Question

I am trying to learn how to use docopt.

Below is my file docopt_test.py. Ideally I should get the passed arguments printed after I run this, but I am only getting output that is printing the usage comment.

Can anyone kindly point me to what am I doing incorrect?

Thanks.

$python3 docopt_test.py client task environment working MCE.zip

Usage:
    docopt_test.py client task environment [--local_tmp_folder=<td>] [--filenm=<filename>]
    docopt_test.py (-h | --help)
    docopt_test.py --version

#docopt_test.py
"""

    docopt_test.py client task environment [--local_tmp_folder=<td>] [--filenm=<filename>]

Options:
  -h --help     Show this screen.
  --version     Show version.
  --entity=<entityname>  specify entity to load

    print(arguments)

I guess I found out what went wrong earlier.

I had put options_first=True while assigning the arguments, but was passing the optional arguments with [ ] at the end. This is the reason docopt was not able to parse my inputs.

Therefore to resolve the issue,

I had to either remove the options_first=True from the arguments

arguments = docopt(__doc__,argv=None,help=True,version=None)

or change the usage comment and provide my input in correct order.
