python自动化办公（4）_邮件自动收发

一、常用的包

如果是本地客户端邮件，安装win32com可实现调用
网页版使用smtplib、email调用

本文收发使用的是办公常会用到outlook，通过win32com调用

二、发邮件

import win32com.client as win32

#调用outlook.application，启动进程
outlook = win32com.client.Dispatch('outlook.application')

#创建一个item，即邮件
mail = outlook.CreateItem()
mail.to = '收件人'
mail.cc = '抄送人'
mail.Subject = '这是一个邮件的主题'
mail.Body = '这是一个邮件的内容'
mail.Attachment.Add("这是附件的路径")
mail.send

三、收邮件

import re
from win32com.client.gencache import EnsureDispatch as Dispatch
import pandas as pd

def read_email(date,my_account):
    
    #读取邮件
    outlook = Dispatch("outlook.Application")
    mapi = outlook.GetNamespace("MAPI")
    Accounts = mapi.Folders
    
    
    #读取账号
    names = []
    #读取内容
    contents = []
