How to add to beginning Python path in bash

Here is my .bash_profile

PYTHONPATH=".:/home/miki725/django/django:$PYTHONPATH"
export PYTHONPATH

So then I open python however the directory I add in .bash_profile is not the first one:

Python 2.4.3 (#1, Sep 21 2011, 20:06:00) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-51)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> for i in sys.path:
...     print i
...

How can I add to a python path in .bash_profile so it would be in the beginning. This is for shared hosting. I need to be able to import my django install instead of using system default.

Thank you

As indicated by others, you modify the sys.path directly in Python like this:

sys.path.insert(0,"/home/miki725/django/django")

But I think that virtualenv is the solution you are looking for. This tool allows you to create isolated Python environments.

I'd say that your PYTHONPATH is being modified when the site module is imported. Please have a look at the user module to provide user-specific configuration (basically just prepend the directories you're interested in to sys.path).

Note: user module is currently deprecated, but for python 2.4 this should work.

Edit: Just for completeness, for python >= 2.6 (user module deprecated), you should create a usercustomize.py file in your local site-packages directory as explained here.

Your best bet is to modify sys.path at runtime. In a shared hosting enviroment it's common to do this in your .wsgi file. You could do something like this:

import sys
sys.path.insert(0, '/home/miki725/django/django')

If you add export PYTHONSTARTUP=/home/miki725/.pythonrc to your .bash_profile, you can add that your .pythonrc file, and it'll be executed before an interactive prompt is shown as well.

As an alternative approach, you could modify sys.path directly from the interpreter:

sys.path.insert(0,"/home/miki725/django/django")
