如何在colab处理完成时发送电子邮件通知

import smtplib
from email.mime.text import MIMEText

sender_email = "your_email@example.com"
receiver_email = "recipient_email@example.com"

subject = "Colab处理完成通知"
body = "您的Colab处理已完成。"
message = MIMEText(body, "plain")
message["Subject"] = subject
message["From"] = sender_email
message["To"] = receiver_email

smtp_server = "smtp.example.com"
smtp_port = 587

username = "your_username"
password = "your_password"

try:
    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    server.login(username, password)
    server.sendmail(sender_email, receiver_email, message.as_string())
    print("邮件发送成功！")
except Exception as e:
    print("邮件发送失败：", str(e))
finally:
    server.quit()
