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
python;gutter:true;
-<em>- coding: utf-8 -</em>-</p>
<p>def prodouct(*num):
n = 1
for x in num:
n = n * x
return n</p>
<p>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))</p>
<p>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')</p>
<pre><code>
方法二：
;gutter:true;
-*- 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’)
