making a module mimic another module

[Gribouillis]

You can create a new module by using the constructor types.ModuleType()

>>> import os
>>> import types
>>> m = types.ModuleType('OS')
>>> for k in dir(os):
...     setattr(m, k.upper(), getattr(os, k))
... 
>>> m.CHDIR
<built-in function chdir>
>>> import sys
>>> sys.modules[m.__name__] = m # optional, if you want to make it importable
>>> import OS
>>> OS is m
True
