A pattern I find myself using frequently, when I do need to ?cd?, is to write a tiny context manager:

import os
from contextlib import context manager

def pushd(path):
    old_dir = os.getcwd()

(I tend to just copy this into projects where I need it (or write it again), as a whole dependency for something so tiny seems like it would be overkill :)
