need help with getopt

i can't seem to understand how to get it to work properly

let's say i have a program program.py that takes 3 options

-t
-q
-s

now t has to take an argument while the arguments for q and s are optional... does it go something like this?

try:
opts, args = getopt.getopt(sys.argv[1:], "t:qs")
except getopt.GetoptError:
usage()
sys.exit(2)
for opt, arg in opts:
if opt == '-t':
#do something
if opt == '-q':
#do something
if opt == '-s':
#do something

As far as I can see, your code is correct. You say you are you having problems getting it working - what is it doing (or not doing)?

A couple of suggestions:

1) if you wrap your code in the post with [CODE] tags then it will be easier for the rest of us to read.

2) You use the name 'args' for the non-option parameters returned from the getopt function, and 'arg' for the value of the option. These could be easily confused, since they are quite different things. I would suggest renaming 'arg' to 'value' or 'optionValue' or something similar.
