There shouldn't be a difference between a shell-script and a 
python-script. Environment-variables are a unix-process-thing, and thus 
the rules that govern them apply to *all* processes - the shell is one 
of these, there is nothing special to it.

If the shell-script gets the variable, the python-script will as well.

Are you sure the shell gets the value? Or is it just silently ignoring a 
missing value, and the python-script isn't? According to the docs (I 
only googled the variable-name), the variable seems only to be set "only 
if local"[1], whatever that means.
