A Python program to generate passwords. Source code mirror from https://codeberg.org/kiichigo/kiurui

Integration of a Python server and a Typescript client using Vite and a development proxy.

Drawing geometric figures with Python turtle graphics.

First steps with the Ursina 3D game engine in Python.

Turtle geometry is a mathematics designed for exploring.

A web application written in Python only — no HTML, no JavaScript — where the state lives on the server and the browser gets a React app you never wrote.

The turtle module provides a visual and intuitive way to simulate biological structures like atoms, molecules and proteins.

A GUI toolkit native to Python and to the operating system.

Tensors are the fundamental building block of machine learning in PyTorch — learn what they are, how to manipulate them, and how to use them on a GPU.

You need to understand variable preference, how to override them, and how to ensure your tests are isolated from the local runtime environment.

Code should have a set of automated tests that let you design new code and modify existing code while verifying that everything still works.

Data with parents and children — QTreeWidget, for when a flat table no longer explains what's there.

pytest cannot run an asynchronous test on its own — the AnyIO plugin is what makes async def test_... execute, and run on two backends.

Rows and columns with QTableWidget — filling them in, selecting them, editing them, and the day you have to move to the model.

Work that takes time without freezing the window — QThreadPool, QRunnable, and why signals are the only way to return with the result.

How the application looks — Qt style sheets, selectors, states, and the style the operating system applies.

How a button lets you know it's been clicked — the mechanism by which Qt widgets talk to each other and to your code.

Drawing what Qt doesn't have — paintEvent and QPainter, a widget you make yourself, and a canvas that remembers what you've painted on it.

The other way of making interfaces with Qt — a separate language, and properties that recalculate themselves.

A whole application — tabs, table, chart, dialogs, files, and an executable, with everything you've learned in these pages.
