It works for me under Windows XP, so I suspect that the hints you've

had an idea - rather than requiring your user to put quotes around the
"*", why not do this:
elif sys.argv[2] in ["*","x","X"]:

Because * is a special character to your shell. Probably your shell is
expanding the * to a list of files. Try printing sys.argv from within
your program

It worked fine for me. Don't forget to put quotes around the * sign or
the shell will substitute.
so:
./calc.py 2 '*' 9
or:
./calc.py 2 "*" 9
or:
./calc.py 2 \* 9
but not:
./calc.py 2 * 9

Thanks Kent and jadrifter, that explains that!
Also thanks for the tips

There's an editing error in my previous message. The corrected
function should not be:
def compute(arg1, arg2, arg3):
if sys.arg2 == "+":
total = add(int(sys.arg1), int(sys.arg3))
print total
elif sys.arg2 == "-":
total = sub(int(sys.arg1), int(sys.arg3))
print t

It works for me.
However, I do have another issue with your code:
> def compute(arg1, arg2, arg3):
>if sys.argv[2] == "+":
>total = add(int(sys.argv[1]), int(sys.argv[3]))
Everything else works + - / but not *
why?
thanks
