'str' object has no attribute 'decode'. Python 3 error?
PythonPython 3.xImaplibPython Problem Overview
Here is my code:
import imaplib
from email.parser import HeaderParser
conn = imaplib.IMAP4_SSL('imap.gmail.com')
conn.login('[email protected]', '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?
Python Solutions
Solution 1 - Python
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:*').
Solution 2 - Python
If you land here using jwt authentication after the PyJWT v2.0.0 release (22/12/2020), you might want to freeze your version of PyJWT to the previous release in your requirements.txt file.
PyJWT==1.7.1
Solution 3 - Python
Begining with Python 3, all strings are unicode objects.
a = 'Happy New Year' # Python 3
b = unicode('Happy New Year') # Python 2
The instructions above are the same. So I think you should remove the .decode('utf-8') part because you already have a unicode object.
Solution 4 - Python
Use it by this Method:
str.encode().decode()

print(html.replace("\\/", "/").encode().decode('unicode_escape'))
Solution 6 - Python
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'
Solution 7 - Python
In Python 3, this mental model is pretty straight-forward:
- Encoding is the process of converting a
strto abytesobject - Decoding is the process of converting a
bytesobject to astr
┏━━━━━━━┓ ┏━━━━━━━┓
┃ ┃ -> encoding -> ┃ ┃
┃ str ┃ ┃ bytes ┃
┃ ┃ <- decoding <- ┃ ┃
┗━━━━━━━┛ ┗━━━━━━━┛
In your case, you are calling data.decode("UTF-8") , but the variable is already a str object and is already decoded. So just refer to data directly if a string is what you need.
Solution 8 - Python
It s already decoded in Python3, Try directly it should work.
Solution 9 - Python
Use codecs module's open() to read file:
import codecs
with codecs.open(file_name, 'r', encoding='utf-8', errors='ignore') as fdata:
Solution 10 - Python
This worked for me:
html.replace("\\/", "/").encode().decode('unicode_escape', 'surrogatepass')
This is similar to json.loads(html) behaviour

If anyone getting the same error while participating in Kaggle for a Logistic REgre, here is the solution :
logmodel = LogisticRegression(solver='liblinear')
Solution 12 - Python
Other answers sort of hint at it, but the problem may arise from expecting a bytes object. In Python 3, decode is valid when you have an object of class bytes. Running encode before decode may "fix" the problem, but it is a useless pair of operations that suggest the problem us upstream.
Solution 13 - Python
I got 'str' object has no attribute 'decode' while creating JWT access_token using Flask_JWT_extended package.
To fix this issue, I upgraded my Flask-JWT-Extended package to Flask-JWT-Extended==4.1.0
For Reference:
Please Visit this page: https://flask-jwt-extended.readthedocs.io/en/stable/

If you are working with Django and simple-jwt: Here is your 100% solution
pip install PyJWT==1.7.1
Solution 15 - Python
my case may have been a bit rare but I was working with django and my project was running locally but not when I deployed it, it seemed as though I was getting multiple dependency errors because I was doing: pip freeze > requirements.txt doing this fixed the issue:
pip3 freeze > requirements.txt
Solution 16 - Python
First install suitable JWT
pip3 install PyJWT
then in your code
token.encode().decode('UTF-8')
this worked me, I think this will help you
