Best method to share Python environments on Windows machine

We have a group of users on a single Windows server (using separate accounts) hoping to create, share and use Python virtual environments for their work.

I know Anaconda has a solution for this:

https://docs.anaconda.com/free/navigator/tutorials/manage-environments/

But I'm curious if there is another, better, easier way to do this which will minimize my time as the sysadmin!

Thanks in advance!

Using Flask/connexion for both web and OpenApi server.

Hi Guys, I had this requirement of writing simple web page for this project. It already hosts Openapi server inside a docker container. I thought of using the connexion app server used by openapi to render the web page too.
My question is when I try to fetch the api from the Javascript if I mention the host as localhost it's getting timed out. But if I give container ip it works fine. Currently I am opening the web page in the same host machine. If I open the web page in different machines what should be the host in this case.

Issues with Pydantic

I've been experimenting with a few Django-related libraries and they all seem to encounter the same problem:

>pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'function'>. Set \\arbitrary\_types\_allowed=True\\ in the model\_config to ignore this error or implement \`\_\_get\_pydantic\_core\_schema\_\_\` on your type to fully support it.\`\`
>
>If you got this error by calling handler(<some type>) within \\\_\_get\_pydantic\_core\_schema\_\_\\ then you likely need to call \`handler.generate\_schema(<some type>)\` since we do not call \`\_\_get\_pydantic\_core\_schema\_\_\` on \`<some type>\` otherwise to avoid infinite recursion.\`\`

The issue occured often when I'm trying to run code that's coming directly from their tutorials, so I'm confused as to whether something changes in Pydantic that's causing these libraries to fail. In this case, I'm testing the `django-ninja` code that appears in their tutorial on `auth` (here):

I made a Python game inspired by "The Password Game", highlighting some of the more obscure aspects of the language. Give it a try and test your skills (or maybe creativity...) 😉

D I'm interviewing Rich Sutton in a week, what should I ask him?

Rich is an author of the RL book, and more recently, he founded the OpenMind Research Institute with some colleagues.

&#x200B;

The interview is in 1 week. I have a background in RL and already have some ideas on questions and topics, but I also want to source questions outside of the Alberta RL bubble. Technical questions are the best, though I am open to anything. Thank you!

&#x200B;

I'll post an update in this thread in a couple weeks after the interview is published.

Server Error (500) in Production of a Django App on Render.com

I am trying to deploy a Django Application on Render.

In my project, I have some number of apps that have their own urls.py file. Then, in the project's url, I included them. Have a look at the project's url:

urlpatterns =
path('admin/', admin.site.urls),
path('', include('home.urls')),
path('about/', include('about.urls')),
path('kbdash/', include('management.urls')),


And for every app the url looks like this:

urlpatterns =
path('', about_page, name='about'),


all these urls work except for the

path('kbdash/', include('management.urls'))

Below is the urls.py of management app:


urlpatterns =
path('', views.Dashboard.as_view(), name='dashboard'),
path('fuels/', views.fuel_list_view, name='fuel_list'),


all the urls in main urls file are working except for the kbdash/

Visiting kbdash/ and any link under kbdash/ throw Server Error (500)

View associated with kbdash/ :

class Dashboard(LoginRequiredMixin, generic.View):

How deploy a Django app?

I'm very close to finish my django project and I'm worried about the deploy. So far, I have an EC2 instance in AWS and even tough it's "online", it's just the EC2 running "python3 manage.py runserver" all the time.

I know this is not the best way, so I wanted to ask you guys:

\-How should I manage my Media/Static files?

\-How should I manage the DB?

\-How should I keep running the app?

\-How can I keep my code updated with my repo in github?

I'm pretty newbie in this deployment field, so I'll appreciate your help and comments :D

PyCharm docker-compose interpreter in WSL

Hey everyone! New coder here.

Building my first web app, I started out with venv in WSL. That worked great for the first 2 months but I've since brought Celery, Mailpit, Redis, and Flower into the equation, which made it very tedious to manage everything manually, so I learned Docker and dockerized my app (I now love Docker, btw :D).

For development, I use Docker Desktop with the WSL-based engine and everything's fine except that I can't configure the Python interpreter in PyCharm to use docker-compose in WSL. The functionality is there but after hooking it all up, it fails with the following errors:

&#x200B;

Over the past 3 days, I've tried reinstalling WSL, Docker Desktop, multiple versions of PyCharm Pro, and seemingly anything in between to no avail.

My question is, has anyone successfully managed to use a Python interpreter hooked to a docker-compose in WSL in PyCharm? I really like PyCharm, but without the above, I can't use the debugger, so I'd probably try running the same setup on native Ubuntu on dual-boot or move to VS Code.

What was for you the biggest thing that happened in the Python ecosystem in 2023?

Of course, there was Python 3.12, but I'm not only talking about version releases or libraries but also about projects that got big this year, events, etc...


EDIT : so nobody cared about pandas 2, mojo or python in Excel ?

dotenv or config.json

I know both will work, but is it better to access your environment variables (SECRET_KEY, EMAIL_USERNAME, etc) using load_dotenv() or json.load(config_file)? In both cases the variables are being imported from outside the website's folder structure, but is one approach inherently safer than the other? If so, please explain why.

How to use Flask with SQLAlchemy Core functions?

I found that SQLAlchemy ORM is not what I need, but AFAIK the Flask-SQLAlchemy module is an ORM based one. How can I use SQLAlchemy with Flask without ORM? Is it enough to setup/configure a SQLAlchemy object at the start of app:

db = SQLAlchemy(app)

then get a connection object from it:

conn = db.engine.connect()

and then use it if it was made by the original (non-flask) sqlalchemy?
