笨方法学python3——习题33

def whileloop(top, stop, step):
    i = 0
    numbers = []

    for i in range(top, stop, step):
        print(f"At the top of i is {i}")
        numbers.append(i)

        i += 1
        print("Numbers now: ", numbers)
        print(f"At the bottom i is {i}")

    print("The numbers: ")

    for num in numbers:
        print(num)


whileloop(0, 7, 1)

以上为练习5，首先定义函数和形参，使用for循环和range函数实现功能，最后调用whileloop函数实现赋值。
