本文介绍了一个使用Python编写的简单猜数字游戏。通过while循环让用户不断输入猜测的整数，并给出相应的提示，直到猜中为止。文章展示了如何用Python实现基本的条件判断和循环控制。

以缩进符和冒号标志语块：

#!/usr/bin/python
#Filename: if.py

number = 23
running = True

while running:
guess = int(input('Enter an integer : '))

    if guess == number:
        print('Congratulations,you guessed it.')
        print('(but you do not win any prizes!)')
        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.')
