Yes—the answer to the problem is right there in the question itself. Please
avoid using Python reserved keywords such as class as identifiers. Your
argparse code has in fact worked correctly: it successfully created an
attribute named class on the args object, but you cannot access it using dot
notation. As is obvious, attempting args.class results in SyntaxError: invalid
syntax.
At the same time, you can verify that the argument does exist by inspecting
(Pdb) vars(args), which shows {'class': 'address'}. The solution is
straightforward: avoid using reserved keywords. You can use an alias such as
cls to resolve this issue.
