4、while循环练习

#从简明Python搬来
number = 23
# 将23赋值给number的变量
running = True
# 在while语句运行前，将running变量设置为ture


while running:
    # 先检查变量running是否为ture，然后再运行相应的块
    guess = int(input(‘Enter an integer : ‘))

    if guess == number:
        print(‘Congratulations, you guessed it.‘)
        # 这将导致 while 循环中止
        running = False
    elif guess < number:
        print(‘No, it is a little higher than that.‘)
    else:
        print(‘No, it is a little lower than that.‘)
else:
    print(‘The while loop is over.‘)
# 在这里你可以做你想做的任何事
print(‘Done‘)
