And it's even nicer (and safer) to highlight the pasted block and put it 
_exactly_ at the indentation level where it should be with C-> and C-<. 
That's why python-mode has those two critical keystrokes, they are vital for 
reorganizing safely the logic of large pieces of code. Far better than 
relying on a keyword-based indentation guess. You do it, and you tell the 
editor exactly where the code should go.
