import smtplib

def send_email(subject, message, recipients):
    # 设置邮件内容
    email_content = f"Subject: {subject}\n\n{message}"

    # 设置发件人和收件人
    sender = 'your_email@example.com'
    password = 'your_email_password'
    smtp_server = 'smtp.example.com'
    smtp_port = 587

    # 连接到SMTP服务器
    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    server.login(sender, password)

    # 发送邮件
    for recipient in recipients:
        server.sendmail(sender, recipient, email_content)

    # 关闭连接
    server.quit()

# 定义邮件主题、内容和收件人列表
subject = 'Hello'
message = 'This is a test email.'
recipients = ['recipient1@example.com', 'recipient2@example.com']
