Tool : marpy the browser IDE.

You start in a browser IDE that is Python-first: virtualenvs, proper dependencies, real logs, not a toy REPL.

See the official webpage.

Python 3.13.0 : ... build full-stack web applications entirely in Python with reflex.

NOTE : Yesterday I tested this framework and it blocked my python running and I couldn't display the result. Interesting about this framework is that you can also program your backend running.

The static motion is green because is not used with RGB colors.

Reflex is a library to build full-stack web apps in pure Python.

Reflex is a Python library designed to build full-stack web applications entirely in Python, eliminating the need to learn JavaScript. It allows developers to create both the frontend and backend of web applications seamlessly, offering flexibility and scalability for projects ranging from simple prototypes to complex systems.

See the GitHub project page.

See my test on Winodws O.S. :

mkdir my_app_catafest

my_app_catafest>python -m venv .venv

It intends to provide solo devs and small teams a solution that allows them to build and operate a website/web app with minimal boilerplate and overhead. All the focus can go to work on the actual product.

News : About my work and one of my websites.

I would like to bring to the attention of those who follow my activity on my websites and appreciate the inability to continue with one of the websites: free-tutorials.org. It is currently hosted on a free host, but I cannot import it 100%, which has led me not to complete it with new posts. The continuation of the activities there, considering the limited time, will be carried out on my blogs with the defined theme with which I started: Linux - Fedora, Graphics, Python, Pygame.

In the meantime, because the host is expensive and until now someone has helped me to host it on his server, it is possible to sell the domain: free-tutorials.org - I receive purchase offers at my personal Yahoo email address catafest@yahoo.com.

Minimum starting price 250 euros, because the domain is old from 2018.
