Python计算几何体的表面积和体积

作为初级学生，这个Python题有点难，任务说还要判断二维和三维的形状，再算其面积和体积，可以方便告诉我吗？真的很感谢！

我给你写了一版，供你参考。如果对你有帮助，望采纳

import math


def square(length, width):
    return length * width, 0

    s = (length * width + length * height + width * height) * 2
    v = length * width * height
    return s, v

    return math.pi * radius ** 2, 0

    s = 4 * math.pi * radius ** 2
    v = 4 * math.pi * radius ** 3 / 3
    return s, v

    s = 2 * circle(radius) + 2 * math.pi * radius * height
    v = circle(radius) * height
    return s, v

    s = circle(radius) + math.pi * radius * math.sqrt(radius ** 2 + height ** 2)
    v = circle(radius) * height / 3
    return s, v
