Python之while循环语句

1、最简单的while循环语句

count = 0
while True:
    count = count +1
    print(count)

2、加上条件判断循环

age = 23
count = 0
while 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+1

print("游戏结束")

3、while循环另类用法（else）

age = 23
count = 0
while 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+1
else:                   #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")
