Change directory in terminal using python

Question

I am writing a simple script to change the current working directory to another directory. The following script works fine until the program exits, after which I will return to my home directory.

#!/usr/bin/python

import os

if __name__ == '__main__':
    os.chdir("/home/name/projects/python")
    os.system("pwd")
    print 'dir changed'

Output:

bash:~$ python chdir.py
/home/name/projects/python
dir changed
bash:~$ pwd
/home/name

I want the directory change to remain even after the program exits. Any ideas how to do this?

Edit : I really want to do this: I often use this directory and instead of doing it cd <path>every time I open the terminal, I just write ./prognameand change the directory.
