如何将电子邮件添加到此脚本

import smtplib
from email.mime.text import MIMEText

# 配置电子邮件服务器
smtp_server = 'smtp.example.com'
smtp_port = 587
smtp_username = 'your_email@example.com'
smtp_password = 'your_password'

# 创建电子邮件对象
sender = 'your_email@example.com'
receiver = 'recipient@example.com'
subject = 'Hello from script'
message = 'This is a test email sent from a script.'

msg = MIMEText(message)
msg['Subject'] = subject
msg['From'] = sender
msg['To'] = receiver

# 发送电子邮件
try:
    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    server.login(smtp_username, smtp_password)
    server.sendmail(sender, receiver, msg.as_string())
    server.quit()
    print('Email sent successfully!')
except Exception as e:
    print('Failed to send email. Error:', str(e))
