| Good news:
| 
| There is a GetEnvironmentVariable() function in the win32api module.
| 
| Bad news:
| 
| There is no SetEnvironmentVariable() function.

See the 'os' module.

>>> import os
>>> print os.putenv.__doc__
putenv(key, value) -> None
Change or add an environment variable.
>>> 

The 'os.environ' attribute is a dict containing all the environment
variables.
