使用 python 将带有附件的 Outlook 电子邮件发送到 Excel 中的用户列表

Question

我可以使用 Outlook 和以下脚本发送电子邮件，但如果我尝试发送附件，则会出现错误。

文件名_Email.xlsx

NAME    EMAIL
Roy     Roy@gmail.com
Jack    Jack@gmail.com

Python脚本

import win32com.client as win32
import pandas as pd

email_list = pd.read_excel(r'C:\Users\roy\Name_Email.xlsx')

names = email_list['NAME']
emails = email_list['EMAIL']

for i in range(len(emails)):
   name = names[i]
   email = emails[i]

   outlook = win32.Dispatch('outlook.application')
   mail = outlook.CreateItem(0)
   mail.To = email
   mail.Subject = 'Message subject'
   mail.Body = 'Hello ' + name
   attachment = "hosts.txt"
   mail.Attachments.Add(attachment)
   mail.Send()

我收到错误：

pywintypes.com_error: (-2147352567, 'Exception occurred.', (4096, 'Microsoft Outlook', 'Cannot find this file. Verify the path and file name are correct.', None, 0, -2147024894), None)

文件名正确，并且与脚本位于同一目录中。

我也尝试更改 Attachment = 'hosts.txt'，但出现同样的错误。不确定缺少什么。

尝试这个

from win32com.client import Dispatch
import win32com
import pandas as pd

def mailprepare():
    num = range(0, 5)
    for kk in num:
        outlook = win32com.client.Dispatch("Outlook.Application")
        for accoun in outlook.Session.Accounts:
            if accoun.SmtpAddress == 'your@mail.com':
                newaccount = accoun
                break
        mail = outlook.CreateItem(0)
        mail._oleobj_.Invoke(*(64209, 0, 8, 0, newaccount))
        data = pd.ExcelFile('D:\\path.xlsx')
        sheet = data.parse('Sheet1')
        name = sheet['Names'][kk]
        mailto = sheet['Mails'][kk]

        att = 'D:\\yourattchment.txt'
        with open(att, 'r') as my_attch:
            myfile=my_attch.read()

        mail.To = mailto
        mail.Subject = 'Subject'
        mail.Body = 'mail body'+ name
        mail.Attachments.Add(att)

        mail.Display(True)
        mail.send

mailprepare()
