smtp_password = 'your_password'

# 邮件内容
msg = MIMEText('Hello, this is a test email.')
msg['Subject'] = 'Test Email'
msg['From'] = 'your_email@example.com'
msg['To'] = 'recipient@example.com'

# 发送邮件
try:
    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    server.login(smtp_username, smtp_password)
    server.sendmail(smtp_username, msg['To'], msg.as_string())
    server.quit()
