Added .vimrc for Python Development

This will make your vim a Python IDE with all the code completion and all.
To make this work, you need to first install the Vundle bundle from git
Bundle 'gmarik/vundle' .. Use git clone and put the folder in .vim/bundle/ folder
Then add the following lines to .vimrc:
Bundle 'gmarik/vundle'
Bundle 'tpope/vim-fugitive'
Bundle 'klen/python-mode'
Bundle 'davidhalter/jedi-vim'

Then install them. Open vim and do :BundleInstall
It will install al the Bundles. You can also use the powerline bundle

Enjoy your Python IDE.
