python 练习题：接收一个或多个数并计算乘积

 以下函数允许计算两个数的乘积，请稍加改造，变成可接收一个或多个数并计算乘积
 def product(x, y):
     return x * y

# -*- coding: utf-8 -*-

def prodouct(*num):
    n = 1
    for x in num:
        n = n * x
    return n

# 测试
print('print(5)=',prodouct(5))
print('print(5,6)=',prodouct(5,6))
print('print(5,6,7)=',prodouct(5,6,7))
print('print(5,6,7,9)=',prodouct(5,6,7,9))

if prodouct(5) != 5:
    print('测试失败')
elif prodouct(5,6) != 30:
    print('测试失败')
elif prodouct(5,6,7) != 210:
    print('测试失败')
elif prodouct(5,6,7,9) != 1890:
    print('测试失败')

方法二：

# -*- coding: utf-8 -*-

def prodouct(x,*num):
    if len(num) > 0 :
        for y in num:
            x = x * y
    return x

# 测试
print('print(5)=',prodouct(5))
print('print(5,6)=',prodouct(5,6))
print('print(5,6,7)=',prodouct(5,6,7))
print('print(5,6,7,9)=',prodouct(5,6,7,9))

if prodouct(5) != 5:
    print('测试失败')
elif prodouct(5,6) != 30:
    print('测试失败')
elif prodouct(5,6,7) != 210:
    print('测试失败')
elif prodouct(5,6,7,9) != 1890:
    print('测试失败')
