I am VERY confused by pythons variables.
def split_check(total, number_of_people): cost_per_person = math.ceil(total / number_of_people) return cost_per_person
amount_due = split_check(84.97, 4)
print("Each person owes ${}".format(amount_due))
so in the first line- split_check equaling the total / number of people makes sense. so why do we create a new variable called cost_per_person which would equal the same exact thing as the split_check variable, which is also the same exact thing as the newest variable amount_due. Why are we not calling of this split_check, instead of renaming it 2 times as cost_per_person and amount_due?

231,236 PointsThe extra variables are probably used to break the process down into simple steps for easier understanding. But you are correct that the process can be condensed down to avoid the use of the variables, for example this code would perform exactly the same as the original:
def split_check(total, number_of_people):
return math.ceil(total / number_of_people)
print("Each person owes ${}".format(split_check(84.97, 4)))
