March Madness Challenge - Day 2

Ok. Time was a bit of challenge today. I wanted to learn more about getopt, and figure out how it differed from optparse. I definitely learned about some of those differences. So tonights program uses getpass to collect a username, password combination. This is pretty unoriginal, but it did help me learn about getopt. I would like to try variation on determining mandatory fields, optional fields, and fields in combination.

#
# Hello World Get Opt for Python
#
#
import getopt
import sys
import getpass

#Describe usage
def usage():
 print "-h, --help\n -v, --verbose\n -u, --username\n -p, --password\n"

def main():
 try:
  opts, args = getopt.getopt(sys.argv[1:], "h:u:pv", ["help", "username=", "password"])
 except getopt.GetoptError, err:
  #print help information and exit:
  print str(err) # will print something like "option -a not recognized"
  usage()
  sys.exit(2)
 username = None
 password = None
 verbose = False

 for o, a in opts:
  if o == "-v":
   verbose = True
  elif o in ("-h", "--help"):
   usage()
   sys.exit()
  elif o in ("-u", "--username"):
   username = a
   print "username: " + username 
                elif o in ("-p", "--password"):
   password = getpass.getpass("Enter password: ") 
   print "password: " + password 
  else:
   assert False, "unhandled option"

 main()
