c2 = list(reversed(c1))

@victorhck perdon, retorna un iterator, asi tiene que expandir la lista.

c2 = reversed(c1)
print(list(c2))

"The reverse() method modifies the sequence in place for economy of space when reversing a large sequence. To remind users that it operates by side effect, it does not return the reversed sequence."

@victorhck reversed(c1)

@victorhck creo que reverse tiene efecto "inplace" asi retorna None, pero el objecto originao si esta modificado.
