随机产生10-30之间的整数，存储到列表中，求它们的阶乘之和

def foo(m):
    if m==1 | m==0 :return 1
    result=1
    while m>0:
        result*=m
        m-=1
    return result   

import random
lst=[]
for i in range(5):
  lst.append(random.randint(10,30))
sum=0
for x in lst:
    sum+=foo(int(x))
    print("%d !=%d"%(x,foo(int(x))))
print(sum)
