This is not possible to do directly.
There is however a possibility to solve this problem under special
circumstances.
1. Your python (/perl/shell/etc) script must write the wanted
environment
variables to standard out, as key-value pairs with a suitable separator.
2. The invoking shell must agree with your script as to what
separator is used.
3. In the calling shell do myshellvars=`your_python_script`;
4. Now the calling shell can parse the variable myshellvars to set
up the environment.
