Auto-load a module on python startup

Question

I want IPython or the Python interpreter to auto-load a module when I start them.
Is it possible?

For example when I start IPython:

$ ipython

...

>>> from __future__ import division
>>> from mymodule import *

In [1]:

Something like this.

Thanks!

Answer 1

Check the file ~/.ipython/ipythonrc - you can list all modules you want to load at the startup.

Answer 2

Have a .pythonstartup in your home directory and load modules there 
and point PYTHONSTARTUP env to that file.

Python commands in that file are executed before the first prompt is displayed in interactive mode.

I use it for enabling command line completion in python interpreter shell
