I have heard this request now a bazillion times over the years. Why don't we have such an empty class sitting somewhere in the stdlib with a constructor classmethod to simply return new instances (and if you want
to
get really fancy, optional keyword arguments to update the instance with the keys/values passed in)? Is it simply because it's just two lines of Python that *everyone* has replicated at some point?
In this case, it's because sys is a built-in module written in C, and importing Python code is a no-go.
Sure, but couldn't we define this "empty" class in C code so that you can use the C API with it as well and just provide a C function to get a new instance? -Brett
We have a similar problem with ABCs: io jumps through hoops to register its implementation classes with the I/O ABCs.

Antoine.
