I haven't checked if it's possible, but I suggest Argparse have it's own exception class that inherits from SystemExit and that exception would be thrown.

ParseError, or something similar.

I suggest this just because it would be more readable I guess and would exactly explain why this code exits.

About exit(), I agree with others about wanting to catch the exception myself and then choosing to exit from the code.  I'm not sure that it's actually useful in practice, though...it might just feel cleaner but not actually be that helpful. As others have pointed out, if you want to do that then you can just catch SystemExit.
