第一章作业

#import getpass

1、猜年龄，可以让用户最多猜三次;

age = 56
n = 0

while n < 3:
    guess_age = int(input ("pls input your guess_age(u get three times):"))
    n = n + 1
    if guess_age > age:
        print("pls smaller")
    elif guess_age < age:
        print("pls bigger")
    else:
        print("u got it!")

#每隔三次，问他一下，还想不想继续玩；y,n

age = 56
n = 3
a = 0
while 0 == n%3 :
    dis = input("pay or not:")
    if dis == "y":
        while 1 == 1:
            n = n + 1
            guess_age = int(input("let's start again:"))
            if guess_age > age:
                print("pls smaller")
            elif guess_age < age:
                print("pls bigger")
            else:
                break
    else:
        break
