1、最简单的while循环语句

count = 0while True: count = count +1 print(count)2、加上条件判断循环

age = 23count = 0while count < 3: age_guess = int(input("请输入数字：")) if age_guess == age : print("你猜对了啦") break; elif age_guess > age : print("你猜大了") else: print("你猜小了") count = count+1print("游戏结束")3、while循环另类用法（else）

age = 23count = 0while count < 3: age_guess = int(input("请输入数字：")) if age_guess == age : print("你猜对了啦") break; elif age_guess > age : print("你猜大了") else: print("你猜小了") count = count+1else: #当while判断不成立时，运行else语句 print("你输入的次数太多啦") print("游戏结束")
