Command line argument parsing library for python

Project description

Argument parsing for python developers


import argument
f = argument.Arguments()
#Requried arguments, first argument will be stored as "candy"
f.require("candy", help="Candy name")

#optional unnamed value

#optional value, set a default, can be changed by adding: --num=30, or -n=30
    help="How many pieces?",
#add a switch, a flag with no argument
    help="Reverse ordering",
f.switch("unwrap", help="unwrapcandy", abbr="u")

#Process data before saving it
f.process("candy", lambda x: x.upper())

#Parse num as integer
f.process("num", lambda x: int(x))

f.validate("num", lambda x: x > 10)

#get data
arguments, errors = f.parse()
