No, because this only changes the directory within Python. This script is 
to replace a shell script.

I have both and read them both first but couldn't find enlightenment. BeOS 
has a bash (2.03) shell so this is essentially a "posix" question and "cd" 
is obviously a built-in command. Is it still possible to call "cd" from 
within Python?
