本文為大家分享了python查看微信消息撤回的具體代碼，供大家參考，具體內(nèi)容如下

1.安裝itchat

itchat是一個(gè)開(kāi)源的python微信庫(kù)，支持發(fā)送消息、圖片、視頻、地圖、名片、文件等，還可以實(shí)現(xiàn)自動(dòng)回復(fù)等多種功能。

看到的一個(gè)文檔還不錯(cuò)

1）.先安一個(gè)python 下載地址

2）.安裝成功之后，進(jìn)入pip3.exe所在的目錄

安裝itchat：pip3.exe install itchat 下圖我的已經(jīng)安裝過(guò)了（注意：使用3以及以上版本執(zhí)行）。

3.打開(kāi)cmd拖入按回車(chē)就好了

代碼實(shí)現(xiàn)

建一個(gè)wx.py文件，以下代碼導(dǎo)入
