How to install/uninstall/update a homemade Python module?

Question

I wrote a small module that has this structure:

~/
   a/
      b/
         foo/
            __init__.py
            foo.py
            bar.py

Each time I use my module - I have to go in its folder and start my interactive session:

$ cd ~/a/b
$ ipython

In [0]: from foo import *

I would like to easily make available my module globally on my PC. Do I need to structure it as package with a setup.py and execute python setup.py install after each change on my module?

Another solution that I don't really like is adding the following to my ipython profile:

import sys
sys.path.append("~/a/b")

Or modifying my PYTHONPATH :

export PYTHONPATH=$PYTHONPATH:$HOME/a/b

是的，将其作为python软件包全局安装或使用virtualenv
