Python Test 220: Getting the most out of PyCon, including juggling - Rob Ludwick

Listen at https://podcast.pythontest.com/episodes/220-juggling-pycon
Even if you never get a chance to go to PyCon, I hope this interview helps you get a feel for the welcoming aspect of the Python community.

The juggling at PyCon is one of the inspirations for PythonPeople.fm, one of PythonTests's sibling podcasts.

Do you have any conference tips to add?

Any preferred stacks people have for quick-starts to a personal project?

I usually start with cookiecutter to create a docker, django/drf, postgres, celery/flower/redis, traefik/nginx stack I can get going quickly on Heroku. However, I'm starting to rethink Docker now that I use Kubernetes more for production (and Heroku got rid of free tiers). Any recommendations that are quick and easy to manage locally and in prod?

What is next?

Hey everyone. I have learnt basic of Django. How to get payments, email verification, password reliad, profile, things to create a marketplace. Now I am planning on celery and nginx for deployment.
My stack is Django, DRF, Git, PostgreSQL, and extensions for Django (django-email, stripe, etc).
So what is after celery and nginx? Can I get a job? Or I have to know Docker, Redis technologies?

Django works locally, not in prodduction

Django works perfectly on a local machine with an in-prod database and saves data, but it's not working in production (same in-prod database)

**Server log**

- connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory
- Is the server running locally and accepting connections on that socket?

**Settings**

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': os.getenv('DB_NAME'),
'USER': os.getenv('DB_USER'),
'PASSWORD': os.getenv('DB_PASSWORD'),
'HOST': os.getenv('DB_HOST'),
'PORT': os.getenv('DB_PORT'),
}
}
DATABASE_URL = os.getenv('DATABASE_URL')

**.env**

DATABASE_PRIVATE_URL={{DATABASE_PRIVATE_URL}} // NOT USING THIS
DATABASE_URL=postgresql://postgres:{{DB_PASSWORD}}@{{DB_HOST}}:19232/railway

Which OS should I strongly use?

I am a fulltime backend Django developer and most of the time I work on making REST APIs. My current OS is Windows 11. In my another secondary laptop I have Ubuntu. Should I need to completely set Ubuntu in my primary laptop too? What are you suggestions? If i need to go for Ubuntu why? As a dev using Linux is compulsory or ?

Django & ReactJs : is ReactJs necessary ?

Hello all.
Am a django developer a year ago, recently i was curious about ReactJs and i created a two projects using both stacks.
But i came to realize that i dont really need ReactJs cause django's templating system exist, with it integrating a frontend would be easy and will never take a long time besides it really do the job.
So what do you think about django alone,
Is it a fullstack framework or you really need ReactJs for your django projects?

I've started writing Python bindings for lexertl

See https://github.com/BenHanson/pylexertl

I will see about registering as an official library when I am happy I have completed all the bindings. I added all the missing functions for the rules objects today, so things are in reasonable shape already.

My python experience has been limited up until now, but it is big for my new role.

I have a runtime parser generator https://github.com/BenHanson/parsertl17 which I also plan to add bindings for.

I hope this is of interest to somebody!

What My Project Does

Allows you to build lexical analysers at runtime and use them to lex text (in this case utf-8)

Target Audience

The C++ library has been used in production for over 10 years.

Comparison

I'm not aware of any competing library.

is gunicorn slow for you? Try with -k 'gevent'

Gunicorn --bind 0.0.0.0:8000 app.wsgi was so slow on vps, like 30s waiting for response, while python manage.py runserver took 500ms.

Try this:

pip install gevent

Gunicorn --bind 0.0.0.0:8000 -k 'gevent' app.wsgi


I don't see this one in tutorials that's why I am putting here for future google searchers

relax-py - Web framework for htmx with hot module replacement

Excited to finally showcase this!

It's still pretty rough around the edges, but I'm finally happy enough with the feature set and curious to see what the community thinks about a framework like this.

Code: [github.com/crpier/relax-py](http://github.com/crpier/relax-py)

Documentation: [crpier.github.io/relax-py](http://crpier.github.io/relax-py)

**What My Project Does**

`relax-py` is a Python framework for building full-stack applications with `htmx`

It provides tools for writing HTML in a manner similar to [simple\_html](https://github.com/keithasaurus/simple_html) (which also inspired the decision to use standard Python to write HTML, rather than use `Jinja2` or to make something like [templ](https://github.com/a-h/templ) work in Python)

It has:

* Hot Module Replacement (meaning, when you update the code that generates HTML templates, the browser also updates instantly) - see the video in the documentation for a quick demo of this
* URL resolution with type hinting - you can get the URL of an endpoint to use in your templates by using the function that handles that URL, and get help from static typing (for example, for putting path parameters in the URL)
* Helpers for dependency injection

In essence, this framework is just a bunch of decorators and functions over [starlette](https://www.starlette.io/), meaning everything that starlette has can be used alongside the framework.

**Target Audience**

Developers interested in building web applications with `htmx` that like new shiny things

Pip 24.1 beta released, and it's a big one

I'd like to call attention to pip 24.1 beta asit is unusual for the pip team to release betas:

https://pip.pypa.io/en/latest/news/#b1-2024-05-06
https://pypi.org/project/pip/24.1b1/

You can install with:

python -m pip install pip==24.1b1

In particular they have upgraded their vendored version of packaging from 21.3 to 24.0, this was a big effort and fixed many bugs, included significant performance improvements, and will allow pip to support free threaded packages. However, it also means legacy versions and specifiers are no longer compatible with pip.

Because this was such a big land the pip maintainers have released a beta in the hopes people will test their workflows, and if something fails in an expected way report their steps as best as possible back to pip: https://github.com/pypa/pip/issues

I've been testing, and contributing a little bit, to the improved performance in this release, it is most noticeable on large dependency trees or long backtracking. For example, a dry run of "apache-airflowall" using cached packages on my machine goes from ~418 seconds to ~185 seconds.
