定期通过电子邮件发送python脚本输出的好方法是什么？

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

sender = 'sender@example.com'
receiver = 'receiver@example.com'
subject = 'Python脚本输出'
message = '这是Python脚本的输出结果。'

msg = MIMEMultipart()
msg['From'] = sender
msg['To'] = receiver
msg['Subject'] = subject
msg.attach(MIMEText(message, 'plain'))

attachment = MIMEText(open('output.txt', 'r').read())
attachment.add_header('Content-Disposition', 'attachment', filename='output.txt')
msg.attach(attachment)

smtp_server = 'smtp.example.com'
smtp_port = 587
username = 'your_username'
password = 'your_password'

with smtplib.SMTP(smtp_server, smtp_port) as server:
    server.starttls()
    server.login(username, password)
    server.sendmail(sender, receiver, msg.as_string())
