'str' object has no attribute 'decode&

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 point I get the error message

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

Python 3 doesn't have decode anymore, am I right? how can I fix this?

Also, in:

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

I am selecting only the 1st email. How do I select all?

Answer 1

Use it by this Method:

str.encode().decode()

Answer 2

It s already decoded in Python3, Try directly it should work.

Answer 3

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

Simply drop the .decode('utf-8') part:

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

As for your fetch() call, you are explicitly asking for just the first message. Use a range if you want to retrieve more messages. See the documentation:

The message_set options to commands below is a string specifying one or more messages to be acted upon. It may 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'). A range can contain an asterisk to indicate an infinite upper bound ('3:*').

Answer 4

I'm not familiar with the library, but if your problem is that you don't want a byte array, one easy way is to specify an encoding type straight in a cast:

>>> my_byte_str
b'Hello World'

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

Answer 5

Begin with Python 3, all string is unicode object.

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

the code before are same. So I think you should remove the .decode('utf-8'). Because you have already get the unicode object.
