Using environment variables in Python

Question

I have an environment variable called %CCDeviceID%. When I run a command using python in Command Prompt, I want to be able to use this variable, and including %CCDeviceID% in the script doesn't work. How can I implement environment variables into my python script?

Thanks Ed

Use os.environ:

import os
print os.environ['CCDeviceID']

You can get a listing of all environment variables available to you simply by doing the following:

>>> import os
>>> print os.environ

os.environ is a dictionary mapping env variable name to its value In your case, you probably need to omit the % symbols. To get CCDeviceID.
