ipython-playground 0.4.1

Understand what is in your ipython playground.

IPython Playground

I'm a big fan of playgrounds. Every repo should have a playground.py to make it easy to jump right into REPL-driven development.

However, it's hard to understand what's in the playground.py once it gets big. This project eliminates this problem (example from this project):

Installation

pip install ipython-playground

Usage

1. Run ipython-playground to generate a playground.py.
2. Execute ./playground.py to start an IPython session with additional setup.

How extras.py and the all() hook work

The ipython_playground/extras.py file provides logic to automatically import and expose useful modules and objects in your playground session. The main entry point is the all() function, which:

• Loads common app modules (like app.models, app.commands, app.jobs) if available.
• Attempts to import helpful libraries such as funcy_pipe, sqlalchemy, and sqlmodel.
• Optionally discovers all SQLModel classes in your models module and adds them to the namespace.
• If a database URL is available (either passed in or imported from your app config), sets up a SQLAlchemy engine and session, and exposes helpers for running and compiling SQL statements.

When you run playground.py, it calls globals().update(ipython_playground.all_extras()), which injects all these objects into your interactive session, making them immediately available for experimentation.
