First one:

    for i in range(4):
         return (1 << i)

Second one:

for i in range(4):
     return (2^i)

Can someone explain why there’s a difference between the 2?

    Because the power syntax is ** not ^:

    >>> [2**i for i in range(4)]
[1, 2, 4, 8]
>>> [1 << i for i in range(4)]
[1, 2, 4, 8]

    Note: ^ (hat) is for bitwise exclusive or.
