Re: Challenging argparse with keyword dest="class"

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.
