因為中國天氣網(wǎng)的網(wǎng)頁是動態(tài)生成的，所以不能直接爬取到數(shù)據(jù)，需要先使用webdriver打開網(wǎng)頁并渲染完成，然后保存網(wǎng)頁源代碼，使用beautifulsoup分析數(shù)據(jù)。爬取的數(shù)據(jù)包括實時溫度、最高溫度與最低溫度、污染狀況、風(fēng)向和濕度、紫外線狀況、穿衣指南八項數(shù)據(jù)。

相比于中國天氣網(wǎng)，微博熱搜要簡單很多，直接request得到數(shù)據(jù)包，然后使用beautiful解析。解析數(shù)據(jù)后用for循環(huán)便利50次保存文本。
使用win32gui自動化操作發(fā)送微信消息，首先使用微信的窗口名找到微信句柄，然后模擬鍵鼠搜索聯(lián)系人，打開聯(lián)系人窗口，發(fā)送消息并關(guān)閉窗口。同時發(fā)送多個聯(lián)系人時可以直接重復(fù)這幾步操作
