python之从 Python 中的 message_from_string() 获取发件人地址

有人可以告诉我如何在 Python 中从 email.message_from_string() 获取发件人地址吗？谢谢!我试过了

message = email.message_from_string(email_text) 
from = message['From'] 

然而，这似乎并没有奏效。

这是我正在解析的电子邮件:

请您参考如下方法:

from 是保留关键字。使用不同的变量名。您的代码在其他方面工作正常:

>>> import email 
>>> message = email.message_from_string(email_text) 
>>> message['From'] 
'Taylor Lovett <tlovett88@gmail.com>' 
>>> from = message['From'] 
  File "<stdin>", line 1 
    from = message['From'] 
         ^ 
SyntaxError: invalid syntax 
>>> from_address = message['From'] 
>>> from_address 
'Taylor Lovett <tlovett88@gmail.com>'
