Python 3向客户发送祝贺

我如何通过电子邮件向我们的客户发送生日祝贺和随附的jpg文件？ 我写脚本，他显示通知：

import time
import os

birthdayFile = 'birthdays.csv'

def checkTodaysBirthdays():
    fileName = open(birthdayFile, 'r')
    today = time.strftime('%m%d')
    flag = 0
    for line in fileName:
        if today in line:
            line = line.split(' ')
            flag =1

            os.system('notify-send "Birthdays Today: ' + line[1]
            + ' ' + line[2] + '"')
    if flag == 0:
            os.system('notify-send "No Birthdays Today!')

但我不知道，如何通过电子邮件发送祝贺。

文件

birthdays.csv

包含下一行：

日期、姓名、电子邮件

您可以使用

smtplib

。下面是一个简单通知系统的实现，它使用一个类来利用clean context manager behavor：

import datetime
import smtplib, csv
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email import Encoders

class SendEmail:
  def __init__(self, _to, _from = 'youremail@domaim.com', subject = 'Happy Birthday!', attachment = 'birthday.jpg'):
    self._to = _to
    self._from = _from
    self._subject = subject
    self.attachment = attachment
  def __enter__(self):
    msg = MIMEMultipart()
    for part in ['Subject', 'From', 'To']:
       msg[part] = getattr(self, f'_{i.lower()}')
    part = MIMEBase('application', "octet-stream")
    part.set_payload(open(self.attachment, "rb").read())
    Encoders.encode_base64(part)
    part.add_header('Content-Disposition', f'attachment; filename="{self.attachment}"')
    msg.attach(part)
    server = smtplib.SMTP(self.EMAIL_SERVER)
    server.sendmail(self.EMAIL_FROM, self.EMAIL_TO, msg.as_string())
    return self
  def __exit__(self, *args):
    pass
  @classmethod
  def send_bulk(cls, users:list):
    for date, name, email in users:
      _d = datetime.datetime.now()
      if _d.month in date and _d.day in date:
        with cls(email, subject = f'Happy Birthday, {name}!') as f:
          pass

with open('filename.csv') as f:
  SendEmail.send_bulk(csv.reader(f))

首先，您真的不应该在

os.system

中使用字符串连接。想象一下，如果有人将自己的生日设置为

；rm-rf/#！其次，查看Python包含的smtplib:。
