Change folder in python3 script using a bash command

I trying to change the path where I located in a python3 script using a bash command. I use this small code but it doesn't work:

import subprocess

args = ['cd', '/foo/bar/xxx']
subprocess.Popen(args)

I also try to use subprocess.call() and subprocess.run() but it doesn't change the path

By doing running those commands, you are launching a new process, which changes its directory to /foo/bar/xxx, then exits. To affect the path of the parent program, use os.chdir like so:

import os
os.chdir('/foo/bar/xxx')

Fun fact: this is why bash and other shells have cd as a builtin; any program equivalent to cd could only affect its own path.
