That "if" line needs to be at top-level. Once you're inside main(),
it's a little late to decide whether to call main().
def user_input():
....
def main():
user_input()
if __name__ == "__main__":
main()

Easiest way to get that is to use the format() method of str.
msg = "A sentence has {0} and {1}".format(arg1, arg2)
Then you can print msg.

Actually, we're all volunteers here, and not part of a team. More like
