Final answer:
The function can be completed using the modulo operator (%). If the remainder is zero, it means that the potential_factor divides into the number evenly, making it a factor. If the remainder is not zero, then the potential_factor is not a factor.
Step-by-step explanation:
The function can be completed using the modulo operator (%). When the modulo operator is used, if the remainder is zero, it means that the potential_factor divides into the number evenly, making it a factor. If the remainder is not zero, then the potential_factor is not a factor.
Here is the correct implementation:
def is_a_factor(number, potential_factor):
return number % potential_factor == 0
