You can do what you suggest without shell scripting, unless I
misunderstand your intention: just set the environment variables you
want your Python script to see and then run it using os.system():
::::::::::::::
one.py
::::::::::::::
import os
os.environ['STEVE'] = "You are the man"
os.system("python two.py")
print "Ran one"
::::::::::::::
two.py
::::::::::::::
import os
print "STEVE is", os.environ['STEVE']
print "Ran two"
[sholden at headrat tmp]$ python one.py
STEVE is You are the man
Ran two
Ran one
[sholden at headrat tmp]$
Hope this helps.
regards
Steve
