[New-bugs-announce] [issue39076] Use types.SimpleNamespace for argparse.Namespace

[Eric Snow]

New submission from Eric Snow <ericsnowcurrently at gmail.com>:

types.SimpleNamespace does pretty much exactly the same thing as argparse.Namespace.  We should have the latter subclass the former.  I expect the only reason that wasn't done before is because SimpleNamespace is newer.

The only thing argparse.Namespace does differently is it supports the contains() builtin.  So the subclass would look like this:

class Namespace(types.SimpleNamespace):
    """..."""
    def __contains__(self, key):
        return key in self.__dict__

Alternately, we could add __contains__() to SimpleNamespace and then the subclass would effectively have an empty body.
