It may be simpler than that:

planck[~/test]> cat env.py
#!/usr/bin/env python
import os

print 'before'
os.system('env | grep TEXMFOUTPUT')

os.environ['TEXMFOUTPUT'] = '/some/path'

print 'after'
os.system('env | grep TEXMFOUTPUT')
planck[~/test]> ./env.py
before
after
TEXMFOUTPUT=/some/path
planck[~/test]>
