Each module has its own namespace.  Why config throws an error is
because even though you imported 'os' in the cli module you are
calling an os function from a different module.  You can however put
them all together in a different manner if this helps:

#fp.py
import cli

#cli.py
import os

#config.py
import cli
print cli.os.environ['HOME']

if you wish to use the os module loaded by the cli module
