如何在Python中打印电子邮件正文中的多行字符串变量

Question

我有这段代码：

l = ["Jargon", "Hello", "This", "Is", "Great"]
result = "\n".join(l[1:])
print result

输出：

Hello
This
Is
Great

我正在尝试将其打印到电子邮件正文中，如下所示，我将文本作为附件而不是正文获取。谁能告诉我我是否在这里遗漏了什么？

msg = MIMEMultipart()
msg["From"] = emailfrom
msg["To"] = emailto
ctype, encoding = mimetypes.guess_type(fileToSend)
if ctype is None or encoding is not None:
    ctype = "application/octet-stream"   
maintype, subtype = ctype.split("/", 1)
fp = open(file.csv, 'r')
attachment = MIMEBase(maintype, subtype)
attachment.set_payload(fp.read())
fp.close()
encoders.encode_base64(attachment)
attachment.add_header("Content-Disposition", "attachment", fileame='file.csv')
msg.attach(attachment)
msg.attach(MIMEText(result, "plain"))
server = smtplib.SMTP("localhost")
server.sendmail(emailfrom, emailto, msg.as_string())
server.quit()

Answer 1

使用

yagmail

时，它会按预期工作。

import yagmail 

yag = yagmail.SMTP(
  user=conf_yag['user'],
  password=conf_yag['password'])

l = ["Jargon", "Hello", "This", "Is", "Great"]
result = "\n".join(l[1:])

yag.send(emailto, 'test from yagmail', result)


# including attachment
yag.send(emailto, 
         subject='test from yagmail', 
         contents=result,
         attachments='somefile.txt')

其中

conf_yag

存储您的凭据，

emailto

是收件人电子邮件地址，

'somefile.txt'

是文件附件。

Answer 2

在Python中，` ' 表示换行符。 在 python 电子邮件中，“
”表示换行符。

如果你这样做

result = result.replace('\n','<br/>')

应该可以。
