#import getpass

1、猜年龄，可以让用户最多猜三次;

 

 1 age = 56
 2 n = 0
 3 
 4 while n < 3:
 5     guess_age = int(input ("pls input your guess_age(u get three times):"))
 6     n = n + 1
 7     if guess_age > age:
 8         print("pls smaller")
 9     elif guess_age < age:
10         print("pls bigger")
11     else:
12         print("u got it!")

 

 

#每隔三次，问他一下，还想不想继续玩；y,n

 1 age = 56
 2 n = 3
 3 a = 0
 4 while 0 == n%3 :
 5     dis = input("pay or not:")
 6     if dis == "y":
 7         while 1 == 1:
 8             n = n + 1
 9             guess_age = int(input("let‘s start again:"))
10             if guess_age > age:
11                 print("pls smaller")
12             elif guess_age < age:
13                 print("pls bigger")
14             else:
15                 break
16     else:
17         break
