python发送邮件代码

在Python中，你可以使用内置的`smtplib`和`email`库来发送电子邮件。以下是一个基本的示例，展示了如何使用这两个模块创建并发送一封简单的邮件：

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

# 邮件配置
sender_email = 'your-email@example.com'
receiver_email = 'recipient-email@example.com'
password = 'your-password'
smtp_server = 'smtp.example.com'  # 根据你的SMTP服务器填写
subject = 'Hello from Python'
body = 'This is a test email sent using Python.'

# 创建邮件对象
msg = MIMEMultipart()
msg['From'] = sender_email
msg['To'] = receiver_email
msg['Subject'] = subject

# 添加邮件正文
msg.attach(MIMEText(body, 'plain'))

try:
    # 连接SMTP服务器
    server = smtplib.SMTP(smtp_server, 587)
    server.starttls()  # 加密连接

    # 登录邮箱
    server.login(sender_email, password)

    # 发送邮件
    server.sendmail(sender_email, receiver_email, msg.as_string())

    print(f"Email sent successfully to {receiver_email}.")

except Exception as e:
    print(f"Error sending email: {e}")

finally:
    # 关闭连接
    server.quit()

记得替换上述代码中的`your-email@example.com`、`recipient-email@example.com`、`your-password`和`smtp.example.com`为你自己的信息。
