如何使用python在条件满足时发送电子邮件

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

def send_email(sender, receiver, subject, message):
    # 邮件内容
    msg = MIMEText(message, 'plain', 'utf-8')
    msg['From'] = Header(sender, 'utf-8')
    msg['To'] = Header(receiver, 'utf-8')
    msg['Subject'] = Header(subject, 'utf-8')

    # 发送邮件
    try:
        smtp_obj = smtplib.SMTP('smtp.example.com', 25)  # 替换为实际的SMTP服务器地址和端口
        smtp_obj.login('your_username', 'your_password')  # 替换为实际的用户名和密码
        smtp_obj.sendmail(sender, receiver, msg.as_string())
        print("邮件发送成功")
    except smtplib.SMTPException as e:
        print("邮件发送失败：" + str(e))

# 调用发送邮件函数
sender = 'sender@example.com'  # 发件人邮箱
receiver = 'receiver@example.com'  # 收件人邮箱
subject = '邮件主题'  # 邮件主题
message = '邮件内容'  # 邮件内容

send_email(sender, receiver, subject, message)
