如何读取文件附件中的换行符？

Question

我正在尝试发送带有两个csv文件附件的电子邮件。我的问题是，当我打开附件时，没有读取换行符（'\ n'），并且邮件中的文本全部放在一行上。如何获取附件以读取换行符？

我尝试使用不同的换行符。

def mail(to, subject, text, attach):
   msg = MIMEMultipart()
   msg['From'] = config.email_address
   msg['To'] = ", ".join(config.email_recipients)
   msg['Subject'] = subject

   msg.attach(MIMEText(text))

   #get all the attachments
   for file in filenames:
      part = MIMEBase('application', 'octet-stream')
      part.set_payload(open(file, 'rb').read())
      Encoders.encode_base64(part)
      part.add_header('Content-disposition', 'attachment', filename='"%s"' % file)
      msg.attach(part)

   mailServer = smtplib.SMTP("smtp.gmail.com", 587)
   mailServer.ehlo()
   mailServer.starttls()
   mailServer.ehlo()
   mailServer.login(config.email_address, config.email_password)
   mailServer.sendmail(config.email_address, to, msg.as_string())
   mailServer.close()

When reading the attachment, I see "word word word word word" instead of 
"word
word
word
word"
