If you import os you can use os getcwd to get the current working directory  and you can use os chdir to change your directory

You can use the os module    gt  gt  gt  import os  gt  gt  gt  os getcwd     home user   gt  gt  gt  os chdir   tmp     gt  gt  gt  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   edit  Under Windows   set PYTHONPATH  PYTHONPATH  C  My python lib    taken from http   docs python org using windows html   edit 2      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   http   virtualenvwrapper readthedocs org en latest command ref html

Changing the current directory is not the way to deal with finding modules in Python   Rather  see the docs for The Module Search Path for how Python finds which module to import   Here is a relevant bit from Standard Modules section      The variable sys path is a list of strings that determines the   interpreter   s search path for modules  It is initialized to a default   path taken from the environment variable PYTHONPATH  or from a   built-in default if PYTHONPATH is not set  You can modify it using   standard list operations          gt  gt  gt  import sys         gt  gt  gt  sys path append   ufs guido lib python     In answer your original question about getting and setting the current directory    gt  gt  gt  help os getcwd   getcwd          getcwd   - gt  path      Return a string representing the current working directory    gt  gt  gt  help os chdir   chdir          chdir path       Change the current working directory to the specified path
