OptParse is a module introduced in Python2.3 that makes it easy to write command line tools.
You give a description of the options that the program can receive, and OptParse will do reasonable stuff for you.
For example:
1 import optparse
2
3 if __name__=="__main__":
4 parser = optparse.OptionParser("usage: %prog [options] arg1 arg2")
5 parser.add_option("-H", "--host", dest="hostname",
6 default="127.0.0.1", type="string",
7 help="specify hostname to run on")
8 parser.add_option("-p", "--port", dest="portnum", default=80,
9 type="int", help="port number to run on")
10
11 (options, args) = parser.parse_args()
12 if len(args) != 2:
13 parser.error("incorrect number of arguments")
14 hostname = options.hostname
15 portnum = options.portnum
args contains your fixed arguments, options contains your values.
For example, options.portnum would contain the integer 80, in the example above.
