[Siddharta]

I used to be a heavy vim user for python, but now I use Wing IDE. I've 
tried out a number of free IDEs - SPE, Eric3, Scite, Pydev and plain old 
vim - and Wing is just way better. Its not free, but its worth it, 
especially if you do a lot of python programming involving multiple 
files - http://www.wingide.com/wingide/index
