Small factorials Solved Problem code: FCTRL2
import sys def fact(n):
final = n
while n > 1:
final *= n - 1
n -= 1
return final #逻辑严谨,不要忘了return def main():
t = int(sys.stdin.readline())
for n in sys.stdin:
print fact(int(n)) #读取String的转换是一个常见的坑 main()
//第二种,利用现成的库
from math import factorial #熟悉这种调用方法 def main():
t = int(raw_input())
for i in range(t):
print factorial(int(raw_input())) main()
学习
怎么调用外部的库
错误
函数忘了return, 思路不严谨
读取时候忘了类型转换
py的类型转化更为注意,比起有类型规定的C
