我是python的新手。以下是我们用于发送邮件的代码。
import smtplib

from email.mime.base import MIMEBase
from email.mime.text import MIMEText
from email import encoders
To="maniram.220@gmailcom"
Subject="mail through code"
Text="Hai!"
mail_sender="pull@gmail.com"
mail_passwd="ZSDCXFF"
server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.ehlo
server.login(mail_sender,mail_passwd)
BODY='\r\n' .join(['To: %s' % To,'From: %s' % mail_sender,'Subject: %s' % Subject,'',Text])
try:
server.sendmail(mail_sender,[To],BODY)
print("email sent")
except:
print("error sending email")
server.quit()
我需要压缩文件夹中的文件（用户指定的路径），然后将其作为附件邮寄 我怎样才能达到这个目标？
答案 0 :(得分：0)
以下显示可能没有必要压缩整个目录以将其附加到电子邮件中。相反，只需根据需要调整FILE_PATHS变量即可考虑所有文件。或者，您可以自由使用create_attachment自动识别目录，将其压缩，并创建一个名称相同的附件以包含在电子邮件中。
