Peculiar Behaviour of __builtins__
I was trying to call the builtin function min by using getattr(__builtins__,'min') This works at the interpretter prompt However when I called it inside a module that was imported by another module it fails and gives an attribute error print getattr(__builtins__,'min')(range(20)) AttributeError: 'dict' object has no attribute 'min' Also in the interpreter >>>type(__builtins__) but in my module print type(__builtins__) Can anyone help me understand whats going on here?
