【Python 第22课】 函数应用示例

jinss

def isEqual(num1,num2):
    if num1<num2:
        print('too small')
        return False;
    if num1>num2:
        print('too big')
        return False
    if num1==num2:
        print('bingo')
        return True
from random import randint
num=randint(1,100)
print('Guess what I think?')
bingo=False
while bingo==False:
    answer=input()
    bingo = isEqual(answer,num)
Guess what I think?
8
Traceback (most recent call last):
  File "F:/python/py22_1.txt", line 17, in <module>
    bingo = isEqual(answer,num)
  File "F:/python/py22_1.txt", line 2, in isEqual
    if num1<num2:
TypeError: unorderable types: str() < int()    为啥呀？

你是python3吧，python3 input得到的是字符串，不能直接比较，要转换成数字
answer=int(input()) ...

是的！是的！谢谢老师！
