This is the fault of your shell (bash perhaps)? Try this: bash$ echo + + bash$ echo * (a list of files in your current directory here) which occurs because of file-globbing. You have a couple options that occur to me: 1) quote the asterisk: bash$ ./mycode.py 3 "*" 2 which will let Python see it without the shell expanding it 2) use a different character/string such as "3 times 2" 3) pass the whole thing as a quoted string and then let Python do the splitting: bash$ ./mycode.py "3 * 2" a, operator, b = argv[1:].split() print(a,b,c) -tkc -- https://mail.python.org/mailman/listinfo/python-list
