##回接上文
在这里插入图片描述
**上文基本提到了软件的功能，那么现在就来说一下代码。

好了废话不多说直接开干！

计时器部分

这个呢是用python开发的，而且只是使用tkinter开发的，所以相信还是有一定的参考能力的。
奉上代码

    with open (r'D:\time _ show\time _ show\data\data_time.hly','w',encoding='utf-8') as f:

这里是计时器部分，当然这里只是其中一个部分隶属于项目子文件。

项目结构

为了更好的了解，我们来了解一下项目结构：

在这里插入图片描述
这里的Canvas就是计时器，至于datetime我只是把模块移到了项目里面。不要在意。

控制器

代码如下：

壁纸设置

这里你可能已经注意到了这里导入了pil这个库，是的这里要实现的就是壁纸的预览，在tkinter窗口显示。
效果图就不放了，感兴趣的去我先前写的博客看看。爬虫代码如下：

计时器天气显示

说完了控制器，再回来说说计时器；
如图：
‘在这里插入图片描述
在这上面又有一个天气显示，没错这也是一个爬虫。

import urllib.request
import re


def weather():
    html = urllib.request.urlopen(r'http://www.weather.com.cn/weather/101240701.shtml',timeout=5)
    urllib.request.urlcleanup()
    read = html.read().decode('utf-8')

    def get_way(path, string):
        path_way = path
        path_get = re.compile(path_way)
        ture_key = path_get.findall(string, re.M)
        return str(ture_key)

    path_html = '<input type="hidden" id="hidden_title" value=".*"'
    see_html = get_way(path_html, read)
    path_see = 'v.*°C'
    see_weather = get_way(path_see, see_html)
    day = get_way('.*日', see_weather).strip('[\"\']')
    weather = get_way('周.*°C', see_weather).strip('[\']')
    #print(weather)
    return weather

if __name__ =='__main__':
    weather()

数据处理

两个软件之间是少不了数据交流的，这里用了一个最简单的办法，让两个软件去调用一个区域内的数据文件。
不过我这里偷了个懒。
在这里插入图片描述
可以看到我直接将数据写入成一个list，之后直接读取内容，使用eval()这个函数进行转换，这样做是不太正确的请大家注意一下！

SUMMARY

最后这个项目就是这个样子的

在这里插入图片描述
具体的代码已经给出来了，大概就是这个样子。
