def product(x): sum=1 for n in x: sum=sumn print (sum) print ('请输入需要计算乘积的因数：') lst = [] #定义一个空列表
str = input("请输入数值，用空格隔开:")
lst1 = str.split()#lst1用来存储输入的字符串，用空格分割
i = 0
n=int(len(lst1)) print (n) while i <= n-1:
lst.append(int(lst1.pop()))#将lst1的数据转换为整型并赋值给lst
i += 1

print (lst) #打印已转换为整数的数据列表 product(*lst) #调用自定义函数
