卧槽，神操作！一句查询让Python帮忙自己写程序

对于很多初入Python编程的同学们而言，对于Python程序的编写，往往会十分生疏，学会了Python的语法，但是转头就忘了，或者是想实现一个基础的功能，但是程序不知道怎么去写。自己去网上找相应的问题，然后挑选合适的程序进行修改，非常的耗时耗力。

今天，小编就带领大家借助一个新的Python库来解决这个问题，让大家只通过一个问题查询的语句，便可以自动获得对应的程序，省略自己编程带来的烦恼。



 1

一个神奇的库



首先，我们来介绍一下，今天我们的主角，就是howdoi这个库，大家安装的话，也非常的简单，只需要pip install howdoi即可。这个库是如何工作的呢？如下图所示：


卧槽，神操作！一句查询让Python帮忙自己写程序

首先程序会将我们的问题，向cache进行查询，如果存在相应的结果，那么就进行返回，如果不存在的话，就向StackOverflow进行查询，如果查询到了结果，就将查询到的结果返回给程序，并在cache中进行缓存。这就是程序的一个基本的原理，接下来就让大家如何使用这一个库吧。

如何使用


该库的使用也是非常的简单的，如下图所示：

上图就是howdoi库的简单使用的案例，大家只需要输入我们想要查询的问题的关键词，howdoi就可以帮助我们查询。为了更好的方便大家使用，让程序对用户更加的友好，小编特地结合tkinter为大家做了一个查询的界面，如下图所示：

上图中，大家只需要点击帮助，就可以获得用法提示。例如在关键词的末尾加入“-a”，就表示要输出全部的查询结果，“-C”就表示要清除所有的缓存。界面的操作也非常的简单，首先是输入要查询的关键词，然后点击”开始查询“的按钮，结果就会显示在下方的Text当中。
大家就可以直接按照返回的程序进行修改了。例如上图中，小编想利用python实现一个”jpg图片转成GIF图片“的功能，那么我就可以输入 ”jpg to gif python“或者是”jpg to gif python “都是可以的。

有兴趣的小伙伴可以动手试试，不过这个库有一个小小问题，有没有人能猜到，欢迎留言区吱一声。
