Note that altough this is perfectly legal, I would *not* recommend doing  
it unless you have a compelling reason to do so (like providing a single  
public namespace for a package, for example).
Some people choose to remove spurious names, to keep the namespace clean  
if that's important for other usage:

# config.py
import os, sys
startup_dir = os.path.abspath(os.path.dirname(sys.argv[0]))
del os, sys
background_color = "white"
...

# main.py
import config
for key, value in vars(config).iteritems():
   print '%s=%r' % (key, value)
