>>> import os >>> os.getcwd() '/home/user' >>> os.chdir("/tmp/") >>> os.getcwd() '/tmp' 

But if it's about finding other modules: You can set an environment variable called PYTHONPATH, under Linux would be like

export PYTHONPATH=/path/to/my/library:$PYTHONPATH 

Then, the interpreter searches also at this place for imported modules. I guess the name would be the same under Windows, but don't know how to change.

Under Windows: 

set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib 

(taken from http://docs.python.org/using/windows.html)

And even better: use virtualenv and virtualenv_wrapper, this will allow you to create a development environment where you can add module paths as you like (add2virtualenv) without polluting your installation or "normal" working environment.
