how to get the subject of email?

[luofeiyu]

I am in python3.4

typ, data = x.con.fetch(b'1', '(RFC822)') #get the first email
text = data[0][1]
message = email.message_from_string(text).get('subject')

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\Python34\lib\email\__init__.py", line 40, in message_from_string
return Parser(*args, **kws).parsestr(s)
File "D:\Python34\lib\email\parser.py", line 70, in parsestr
return self.parse(StringIO(text), headersonly=headersonly)
TypeError: initial_value must be str or None, not bytes

message = email.message_from_string(str(text)).get('subject')
message # nothing displayed

Try using email.message_from_bytes() instead.

Also have a look at

for a question very similar to yours. Perhaps something in the code
will help.

message = email.message_from_bytes(text)

I get it ,
print(message['Subject']) #can get the subject

But how can i get the body content of message?

no , message['Body'] or message['Content']

Could the answer to your numerous questions be in the docs, in this case
