how to change user's shell current directory using python ? (ubuntu/linux)

Question

We can change the current directory in the shell :

username@hostname:~/f1$ cd ~/f2
username@hostname:~/f2$

is it possible to write a python (v2.7 and / or v3) which changes the current directory to one programatically determined ?

E.g.

username@hostname:~/f1$ python change_dir.py
username@hostname:~/f2$

It is not possible; a child process cannot change the environment of its parent. That's why cd is a shell built-in command. — chepner

As chepner and Sraw correctly said, a child process cannot change the current directory of its parent. So, what you can do is to let the Python program output the desired directory and use this output in a cd command:

cd `python print_dir.py`
