Anonymous Classes

How to create new files?

Hi, I'm trying to create a Python equivalent of the C++ "ifstream" class, with slight behavior changes. Basically, I want to have a "filestream" object that will allow you to overload the '<<' and '>>' operators to stream out and stream in data, respectively. So far this is what I have: class fi
