如何在python3中使用smtplib通过电子邮件发送变量值？

import smtplib
from email.mime.text import MIMEText

def send_email(sender_email, sender_password, receiver_email, subject, variable_value):
    # 创建邮件内容
    message = MIMEText(f"The value of the variable is: {variable_value}")
    message['Subject'] = subject
    message['From'] = sender_email
    message['To'] = receiver_email

    # 连接SMTP服务器
    with smtplib.SMTP('smtp.example.com', 587) as server:
        server.starttls()
        server.login(sender_email, sender_password)

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

# 使用示例
sender_email = 'your_email@example.com'
sender_password = 'your_email_password'
receiver_email = 'recipient@example.com'
subject = 'Variable Value'
variable_value = 42

send_email(sender_email, sender_password, receiver_email, subject, variable_value)
