I didn't see it mentioned (forgive me if I missed it) but you can also assign to slices: >>> n = list(range(10)) >>> n[::3] = 'fizz' >>> n ['f'

I didn't see it mentioned (forgive me if I missed it) but you can also assign to slices: >>> n = list(range(10)) >>> n[::3] = 'fizz' >>> n ['f', 1, 2, 'i', 4, 5, 'z', 7, 8, 'z'] It's weird but occasionally useful.
