Python中If语句与While语句的简单介绍（附示例）

number = 50

max = 100

# input( ) 函数将以字符串的形式返回我们所输入的内容

running = True

while running :

        guess_number = input("请输入猜测的数字：")

        if int(guess_number) == number :

        # if 块从此开始

                print("恭喜你！猜对了!")

                #这将导致 while 循环终止

                running = False

        elif int(guess_number) < number :

        # 另一代码块

                print("很抱歉，你猜小了!")

                print("这个数字是在" + str(guess_number) + "和" + str(max) + "之间")

                min = guess_number

        else :

                print("很抱歉，你猜大了!")

                print("这个数字是在" + str(min) + "和" + str(guess_number) + "之间")

                max = guess_number

print('游戏结束！')
