Unfortunately, to my knowledge you're correct -- subprocesses spawned
from a shell are unable to influence the invoking session. This is the
same for anything -- Python, a bash script, etc.

The only good way I've ever found to "do something useful and update
the current shell env" is to *source* shell scripts via the shell's
"source" function, which cannot be done in Python (the whole point is
for the shell to interpret a shell script "inline", and last I
checked, Bash or Zsh could not interpret Python natively.)

Best,
Jeff
