第一种是最常见的，smtp发送

import smtplibimport sysimport tracebackfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartimport osdef sendEmail(mail_sender, to_list, sub, content, attach_list = [], _subtype="html"):    """    使用smtp发送邮件    :param mail_sender: 发件人    :param to_list: 收件人列表，用,间隔    :param sub: 主题    :param content: 内容    :param attach_list:附件    :param _subtype: 读取内容用的方式，不传html的话改成plain    :return:    """    msg = MIMEMultipart()    msg['subject'] = sub    msg['From'] = mail_sender    msg['To'] = to_list    try:        msg.attach(MIMEText(content, _subtype,'utf-8')) #用html的方法是更方便于Word文档作为内容发送，可以先讲word转换成html，然后写入其中        s = smtplib.SMTP('123.com', 25)        # s.login()        s.starttls()        if attach_list:            for att_path in attach_list:                path_arr = att_path.split(os.path.sep)                file_name = path_arr[len(path_arr) - 1]                att1 = MIMEText(open(att_path,'rb').read(), 'base64','utf-8')                att1.add_header('Content-Disposition', 'attachment', filename=file_name) #用这个方法可以避免附件乱码                msg.attach(att1)        s.sendmail(mail_sender, to_list.split(u','), msg.as_string())        s.close()        print("999921||业务数据处理||邮件发送成功")        return True    except Exception as e:        sys.stderr.write("999931||{}".fORMat(traceback.format_exc(limit=None, chain=True)))        sys.stderr.write("0001")        return False

第二种是用outlook发送的，这个大家借鉴使用

import osfrom time import sleepimport autoit as auimport win32com.clientclass OutlookUtills:    def __init__(self):        outlook = win32com.client.Dispatch("outlook.Application ")# outlook.Visible = True        self.mail = outlook.CreateItem(0)        self.mail.Display()    def sendEmail(self, addressee, subiect, AttachmentsPath=[], body=None):        """        若body为默认值None则自动粘贴剪切板中内容进行发送        :param addressee: 收件人        :param subiect: 主题        :param AttachmentsPath: 附件名称        :param body: 正文        :return:        """        self.mail. To = addressee        self.mail.subject = subiect        if AttachmentsPath == []:            print("该邮件无附件")        else:            for Attachments in AttachmentsPath:                self.mail.Attachments.Add(Attachments)                print("地址：{},附件添加成功!!")        sleep(2)        if body == None:            self.mail.body = ""            au.send('^v')            print("正文已从剪切板拷贝")        else:            self.mail.body = body            print("正文由函数进行输入")        sleep(1)        self.mail.Send()if __name__ == '__main__':    my_outlook = OutlookUtills()

第三种是正文需要用到表格的，我在这里给大家一个示例，具体表格怎么改自行发挥

import smtplibfrom email.mime.text import MIMETextfrom email.header import Headerclass Mail:    def __init__(self):        # 第三方 SMTP 服务        self.mail_host = "smtp.qq.com"  # 填写邮箱服务器:这个是qq邮箱服务器，直接使用smtp.qq.com        self.mail_pass = "ahlwsnkajalubeif"  # 填写在qq邮箱设置中获取的授权码        self.sender = '1004983289@qq.com'  # 填写邮箱地址        self.receivers = ['tianyi.zhang@kingstarfintech.com']  # 填写收件人的邮箱，QQ邮箱或者其他邮箱，可多个，中间用,隔开    def send(self):        self.mail_host = "smtp.qq.com"  # 填写邮箱服务器:这个是qq邮箱服务器，直接使用smtp.qq.com        self.mail_pass = "ahlwsnkajalubeif"  # 填写在qq邮箱设置中获取的授权码        self.sender = '1004983289@qq.com'  # 填写邮箱地址        self.receivers = ['tianyi.zhang@kingstarfintech.com']  # 填写收件人的邮箱，QQ邮箱或者其他邮箱，可多个，中间用,隔开        insert = "152371200010240002潘金莲tar152371200010240002.tar20220426-1545否152371200010240002潘金莲tar152371200010240002.tar20220426-1545否"        head = \            """                                                                    """        body = \            """
