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
