Cannot figure out what is wrong

[wavic]

Consider this:

def pow(number, power): # calculating an exponent
    result = 1
    for _ in range(power):
        result = result * number
   
    # the function always returns a value. If you do not specify what will be that value it will be None.
    # So, you may print it or just generate it some way. But outside of the function, this variable will be untouchable.
    # If you put raw materials in some kind of super duper sophisticated machine it may produce a laptop.
    # But if there is no functionality to get the production out good for you - no laptop. :D
    # So here it is - the return statement
     return result

powers = []
for num in range(1,5):
    power = pow(num, 3) # here the result of the pow() is returned and assgned to a variable.
    powers.append(power)

print(powers)

Output:
[1, 8, 27, 64]
