How to clear os.environ value for only one variable in Python

Question

I'm setting os.environ['PYTHONHOME']="/home/user/OpenPrint/py2.6" in my Python script

But at the end of the script I need to clear this variable so that I can call another python script from a different location. Can someone tell me how to do that? I tried os.environ.clear() but that clears all the other variables too.

Answer 1

Use

os.environ.pop("PYTHONHOME")

See (minimal) documentation at http://docs.python.org/2/library/os.html
