Decode a run-length encoded list. Given a run-length code list generated as specified in problem 11. Construct its uncompressed version.

def decode(encoded):
    for x in encoded:
        if type(x) == tuple:
            for _x in range(x[0]):
                yield x[1]
        else:
            yield x

By now you should know to throw a "list" into the mix if that's the way you swing.
