猜數字遊戲：#!/usr/bin/env python
# -*- coding:utf-8 -*-
age_of_xcn = 20
for i in range(3):
guess_age = int(input("guess age:"))
if guess_age == age_of_xcn:
print("yes,you got it")
break
elif guess_age > age_of_xcn:
print("think smaller")
else:
print("think bigger")
else:
print("bay bay")
執行結果：
guess age:1
think bigger
guess age:2
think bigger
guess age:4
think bigger

當使用者輸入3後則會提示「do you want to keep ?」輸入知道不是n，則count=0，然後重新從0開始迴圈#!/usr/bin/env python
# -*- coding:utf-8 -*-
age_of_xcn = 20
count = 0
while count
guess_age = int(input("guess age:"))
if guess_age == age_of_xcn:
print("yes,you got it")
break
elif guess_age > age_of_xcn:
print("think smaller")
else:
print("think bigger")
count += 1
if count == 3:
confirm = input("do you want to keep ?")
if confirm != 'n':

guess age:1
think bigger
guess age:2
think bigger
guess age:3
