python发送qq邮件带附件

可以使用Python的smtplib和email模块来发送带附件的邮件。下面是一个简单的示例代码：

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

# 邮件配置信息
smtp_server = 'smtp.qq.com'
smtp_port = 465
sender = 'your_qq_email@qq.com'
password = 'your_qq_email_password'
receiver = 'recipient_email@qq.com'

# 构造邮件对象
msg = MIMEMultipart()
msg['Subject'] = 'Python发送带附件的邮件'
msg['From'] = sender
msg['To'] = receiver

# 添加邮件正文
text = MIMEText('这是一封带附件的测试邮件。')
msg.attach(text)

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

# 发送邮件
smtp = smtplib.SMTP_SSL(smtp_server, smtp_port)
smtp.login(sender, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

print('邮件发送成功！')

需要注意的是，QQ邮箱需要使用SMTP_SSL协议发送邮件，所以需要使用`SMTP_SSL`类来创建SMTP对象。同时，为了能够发送附件，需要使用`MIMEMultipart`和`MIMEApplication`类来构造邮件对象和附件对象。在添加附件时，需要指定附件的文件名。
