easy_arg_parse's Introduction

easy_arg_parse

I think a better alternative to argparse

installation

either git pull... then python setup.py install or pip install easy_arg_parse

usage example

# program_that_needs_arguments.py
from easy_arg_parse import easy_arg_parse

if __name__ == '__main__':
    eap = easy_arg_parse.EasyArgParse\
            (
                defined_args=
                {
