try:
    server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
    server.ehlo()
    server.login(gmail_user, gmail_app_password)
    server.sendmail(sent_from, sent_to, email_text)
    server.close()

    print('Email sent!')
except Exception as exception:
    print("Error: %s!\n\n" % exception)

如何在此电子邮件中附加helloword.txt文件？这段代码运行良好，我只想随它一起发送附件。这段代码可以让我发送没有任何附件的尸体。另外，如何加密存储电子邮件地址和密码的key.txt文件，并发送电子邮件要求输入密码（diff pass）？

Answer 1

    from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

mail = MIMEMultipart()
mail["Subject"] = sent_subject
mail["From"] = sent_from
mail["To"] = sent_to
mail.attach[MIMEText(sent_body,'html')]

ctype, encoding = mimetypes.guess_type(_file)
maintype, subtype = ctype.split('/', 1)
fp = open("/path/to/attachment/file.txt")
# If file mimetype is video/audio use respective email.mime module. 
# Here assuming 'maintype' == 'text' we will use MIMEText
msg = MIMEText(fp.read(), _subtype=subtype)
fp.close()
filename = os.path.basename(_file)
msg.add_header('Content-Disposition', 'attachment', filename=filename)
mail.attach(msg)


server.sendmail(sent_from, sent_to, mail.as_string())
