The terms you are looking for are serialization (converting Python objects
to JSON) and deserialization (converting JSON to Python objects).

If you're using requests, and you can successfully run the .json() method,
then you successfully converted the JSON to a native Python structure.

In this case, you are requesting a list of heroes, so you received a list
back. You'll need to find the hero you want in the list using the standard
methods of working with Python lists, access that element, and then you'll
have access to the dict for that hero.

There is probably a way to get a single dict for a specific hero from the
API, but I'm not familiar with their API structure. You'll need to revert
to their API documentation to determine the correct URL structure.

 Hi,

 If you want to parse json in django - or in python for that matter -
 all you have to do is to use the json module.

 import json

 object = json.loads(insert_string_here)

 insert_string_here is the string that you want to parse - and object is
 the parsed json.

 Look here for more information: http://docs.pytho
 n-guide.org/en/latest/scenarios/json/

Re: tutorial p.6 problem: style.css isn't loaded

[Jason]

Correct.  Django's dev server has file watchers looking at the files 
currently in the project when its started, but creating new files doesn't 
add them to said file watchers.  Only solution is to restart the dev server 
process.

Re: makemigration not working

[Andréas Kühne]

Looking at the output you have, it looks like you haven't got django
installed in your virtualenvironment (or you haven't activated your
virtualenvironment before running the command).

Check here:
https://tutorial.djangogirls.org/en/django_installation/

Look for the information about how to create and use a virtualenvironment.

Python 2.7 reaches its end-of-life (in terms of official bug/security
support from the Python core team) in 2020. That is also when Django 1.11's
end-of-life (in terms of official bug/security support from the Django
team) ends.

After that, only Python 3 will be supported by the Python core team. So
only Python 3 will be supported by Django.

Django 2.0 drops support for Python 2 to ensure no Django release can
"outlive" official support for Python 2. If you want to continue using
Python 2 with Django, you must continue using Django 1.11.

Also, it's been almost ten years since Python 3.0 was released, and you
have nearly two more years. Twelve years ought to be enough to make the
switch :)

Hi Etienne,

Python 2.x will not receive any updates (security or otherwise) starting in 
2020. Many projects are dropping python 2 support right now to allow people to 
have enough time to port their codebases to python 3.

'module' object has no attribute 'lru_cache'

[Etienne Robillard]

Hi,

I'm trying to upgrade my development server to Django 2.0 using setup.py 
develop command:


erob@marina:~/ncvs/django$ sudo python setup.py develop
Traceback (most recent call last):
  File "setup.py", line 32, in 
    version = __import__('django').get_version()
  File "/home/erob/ncvs/django/django/__init__.py", line 1, in 
    from django.utils.version import get_version
  File "/home/erob/ncvs/django/django/utils/version.py", line 61, in 


    @functools.lru_cache()
AttributeError: 'module' object has no attribute 'lru_cache'

Why does the setup.py script attempt to import the django package?

Is it possible to upgrade Django from source when release 1.11.6 is 
already installed in /usr/local ?


Thank you in advance,

Etienne
