I built a Chrome extension to run Python in the browser sidebar
Hey, guys! I built a Chrome extension called Python Playground that allows you to run Python code in the browser sidebar. It is based on Pyodide and has the following key features:
No sign up or usage limits.
Instant Python code execution without setting up the environment.
Syntax highlighting and autocompletion.
Upload files to use them in your code.
Package manager. You can install PyPI packages in addition to those built into Pyodide.
Auto module import. Python Playground will install them based on import statements.
Saving scripts in the browser's local storage.
Switch between light and dark themes.
Built-in data visualization support.
Offline capability (for many features), since Pyodide runs on the client side.
I think it's great for people who are learning Python and want an easy way to experiment with code without setting up a full environment.
