Automatic indentation for Python in Notepad++

It doesn't act like Python's IDLE.

Example:

else:  
    name = 'World'
    print 'Howdy', name
    print 'yay'

but in Notepad++

else: # i press enter and this is what it does
lands me here

But I want to be able to do it like in IDLE: after the : I can just press enter and keep on going.

I have my file type set to Python and my format to unix.
