很早之前,无意中我发现二十四节气上的节气壁纸非常的好看。于是我就把壁纸的高清版下载了下来,每到新节气开始的时候就手动设置壁纸。后来为了嫌麻烦,就做了一个由 batch,vbs,和outlook里面写macro 结合的一个小程序,每天判断当天是否是一个新的节气的开始,如果是就自动设当前节气为主题的壁纸,并且将该壁纸embeded 在 outlook邮件中发给我自己。

再后来觉得这么一个个的script文件不好看,就干脆用一个python文件把它们整合起来。

第一步, 把24节气的24张壁纸下载到本地,并以拼音进行命名

节气壁纸

第二步,爬介绍24节气的网页,得到各个节气的日期,名字和简介。

我用的是以下两个网站
page 1
page 2

第三步,判断今天日期是否与其中的节气开始的日期相等,如果相等则准备发邮件和设壁纸

由于该网站上是前三个缩写字母来表示月份,在python里面如何快速将一月份 Jan 转换成数字1 呢?
可以用calendar库里面的month_abbr

import calendar
self.abbr_to_num = {name: num for num, name in enumerate(calendar.month_abbr) if num}
Month_num=self.abbr_to_num[Month]

第四步,用outlook发邮件。

由于我安装的是outlook客户端,所以我可以直接调用 win32 的库来对outlook进行操作
需要注意的是,当插入图片作为附件时,邮件并不会自动展示该图片。但是我想做的是把图片embeded在邮件内容中进行发送,这样接收者不仅可以很清晰的预览该图片,并且可以下载它。

在code里面,我们不仅需要在htmlbody里面插入img标签(注意需要加入cid),
而且需要给邮件的attachment设置 属性:

sttachment = mail.Attachments.Add(attachment_path)
sttachment.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001F", File_name )

第五步,设置壁纸

如果是windows系统,则需要

import ctypes
SPI_SETDESKWALLPAPER = 20 
output=ctypes.windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0, attachment_path , 0)

第六步,每天用windows scheduler 定时运行该程序。
