I wonder how good programmers get command line parameters in Python? What if there are a lot of parameters? 

def main():
    type = None if len(sys.argv) == 1 else sys.argv[1]
    date = None if len(sys.argv) != 3 else sys.argv[2]

  • @Smac89 There isn't a sys.argc :) Commented Sep 17, 2013 at 7:11

    You don't assign 40,000 command line arguments to 40,000 variables. There are things called lists. Commented Sep 17, 2013 at 7:12

Check out argparse, it's replacing optparse.
