python – optparse
March 11th, 2008 by webstersprodigy
This is a module you can use to parse command line options in python.
Foolishly, I used to do something like:
def getopts(argu):
opts = {}
while argu:
if argu[0][0] == '-':
opts[argu0]] = argv[1]
argv = argv[2:]
else:
argv = argv[1:]
return opts
There is a better way, and it’s found in the optparse module. It is very powerful. You can easily alias scripts (eg -q is the same as –quiet). Also, you automatically can add messages to -h or –help, set default values, etc. A good tutorial on it’s usage is http://docs.python.org/lib/module-optparse.html
