使用Python编写发送电子邮件的代码
解析： 1. 首先，我们需要导入Python的内置库smtplib和email.mime.text，这两个库可以帮助我们发送电子邮件。 2. 然后，我们需要设置SMTP服务器的地址和端口，以及发送者的邮箱地址和密码。 3. 接下来，我们需要创建一个MIMEText对象，这个对象包含了我们要发送的电子邮件的内容。 4. 然后，我们需要创建一个SMTP对象，并使用它来连接到SMTP服务器。 5. 接着，我们需要使用SMTP对象的sendmail方法来发送电子邮件。 6. 最后，我们需要关闭SMTP连接。 代码如下： ```python import smtplib from email.mime.text import MIMEText # 设置SMTP服务器地址和端口 smtp_server = 'smtp.example.com' smtp_port = 587 # 设置发送者邮箱地址和密码
