如何根据选择的选项将电子邮件发送到

import smtplib
from email.mime.text import MIMEText
from email.header import Header

def send_email(option):
    # 邮件内容
    mail_content = "这是一封测试邮件"
    message = MIMEText(mail_content, 'plain', 'utf-8')
    message['From'] = Header("发件人", 'utf-8')
    
    if option == 1:
        # 选项1，发送到收件人1
        message['To'] = Header("收件人1", 'utf-8')
        message['Subject'] = Header("选项1的邮件主题", 'utf-8')
        
        # 使用腾讯云的SMTP服务器发送邮件
        smtp_server = "smtp.exmail.qq.com"
        smtp_port = 465
        username = "your_username"
        password = "your_password"
    
    elif option == 2:
        # 选项2，发送到收件人2
        message['To'] = Header("收件人2", 'utf-8')
        message['Subject'] = Header("选项2的邮件主题", 'utf-8')
        
        # 使用腾讯云的SMTP服务器发送邮件
        smtp_server = "smtp.exmail.qq.com"
        smtp_port = 465
        username = "your_username"
        password = "your_password"
    
    else:

        message['To'] = Header("收件人3", 'utf-8')
        message['Subject'] = Header("选项3的邮件主题", 'utf-8')
        
        # 使用腾讯云的SMTP服务器发送邮件

        smtp_port = 465
        username = "your_username"

    try:

        print("邮件发送成功！")
        
    except smtplib.SMTPException as e:
        print("邮件发送失败：" + str(e))
    
    finally:
        # 关闭连接
        smtp_obj.quit()
