Short answer is, no matter how you do it, you can't do it.

The "source" command executes the given file in the *current* shell.  A
Python script, or a Perl script, or for that matter a shell script runs
in a *subshell* and *can not change the parent shell's environment*.
This is a FAQ for shell users somewhere...

BTW this also means that a Python script on Unix/Linux/BSD can't change
the current shell's environment variables either.

Just what, precisely, are you trying to accomplish?  Likely there is some
sort of workaround...
