Python群发特定附件

在Python中，可以使用smtplib和email库来实现群发特定附件的功能。下面是一个简单的示例代码：

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

def send_email_with_attachment(sender_email, sender_password, receiver_emails, subject, message, attachment_path):
    # 创建邮件对象
    msg = MIMEMultipart()
    msg['From'] = sender_email
    msg['To'] = ', '.join(receiver_emails)
    msg['Subject'] = subject

    # 添加正文
    msg.attach(MIMEText(message, 'plain'))

    # 添加附件
    with open(attachment_path, 'rb') as file:
        attachment = MIMEApplication(file.read())
        attachment.add_header('Content-Disposition', 'attachment', filename=attachment_path)
        msg.attach(attachment)

    # 发送邮件
    with smtplib.SMTP('smtp.gmail.com', 587) as server:
        server.starttls()
        server.login(sender_email, sender_password)
        server.send_message(msg)

# 示例用法
sender_email = 'your_email@gmail.com'
sender_password = 'your_password'
receiver_emails = ['recipient1@example.com', 'recipient2@example.com']
subject = '邮件主题'
message = '这是一封带附件的邮件'
attachment_path = 'path/to/attachment.pdf'

send_email_with_attachment(sender_email, sender_password, receiver_emails, subject, message, attachment_path)

请注意，上述示例使用了Gmail的SMTP服务器，如果你使用其他邮箱，请根据相应的SMTP服务器和端口进行修改。
