yum erase python = destruction
===

I'm sure this question will make many laugh, but certainly not me.

I were trying to install some packages for python earlier today and also trying to change pydev compiler in AptanaStudio, and something was not working out. So I decided to completely remove python from the computer (I ran Fedora 10) by running 

    sudo yum erase python  

I definitely should have not done this. Even the message that 788 packages would be removed didn't stop me. As a result, I seem to have erased the whole Fedora interface. After a lot of pain, I managed to copy all the important stuff to external hard drive (apparently the hard drive of the computer remained intact), but Fedora doesn't want to start. So here's what I'd like to find out:

1)what exactly happened and why?

2)is it possible to restore the interface somehow? 

thanks
