The str object does not have the decode attribute. Python 3 error?

Question

Here is my code:

import imaplib from email.parser import HeaderParser conn = imaplib.IMAP4_SSL('imap.gmail.com') conn.login('[e-mail]', 'password') conn.select() conn.search(None, 'ALL') data = conn.fetch('1', '(BODY[HEADER])') header_data = data[1][0][1].decode('utf-8') 

at this moment i get an error

 AttributeError: 'str' object has no attribute 'decode' 

Python 3 no longer has decryption, right? How can i fix this?

Also in:

 data = conn.fetch('1', '(BODY[HEADER])') 

I choose only the first letter. How to choose everything?

Answer 1

You are trying to decode an object that is already decoded. You have str , no need to decrypt it from UTF-8.

Just release the .decode('utf-8') :

 header_data = data[1][0][1] 

As for your call to fetch() , you are explicitly requesting only the first message. Use a range if you want more messages. See Documentation:

The message_set parameters for the commands below is a string indicating one or more messages to be received. This can be a simple message number ( '1' ), a range of message numbers ( '2:4' ), or a group of non-contiguous ranges separated by commas ( '1:3,6:9' ). The range may contain an asterisk indicating an infinite upper bound ( '3:*' ).

Answer 2

Start with Python 3, the whole line will be a unicode object.

  a = 'Happy New Year' # Python 3 b = unicode('Happy New Year') # Python 2 

the code is the same before. So I think you should remove .decode('utf-8') . Since you already got a unicode object.

Answer 3

Use it with this method:

 str.encode().decode() 

Answer 4

I am not familiar with the library, but if your problem is that you do not need an array of bytes, one simple way is to specify the encoding type directly in the broadcast:

 >>> my_byte_str b'Hello World' >>> str(my_byte_str, 'utf-8') 'Hello World' 

Answer 5

It is already decrypted in Python3, try it directly, it should work.

Answer 6
