I shall try to show how to set a Bash terminal's working directory to whatever path a Python program wants in a fairly easy way.

Only Bash can set its working directory, so routines are needed for Python and Bash. The Python program has a routine defined as:

fob=open(somefile,"w")
fob.write(dd)
fob.close()

"Somefile" could for convenience be a RAM disk file. Bash "mount" would show tmpfs mounted somewhere like "/run/user/1000", so somefile might be "/run/user/1000/pythonwkdir". "dd" is the full directory path name desired.

The Bash file would look like:

#!/bin/bash
#pysync ---Command ". pysync" will set bash dir to what Python recorded
cd `cat /run/user/1000/pythonwkdr`
