Python Playground
What Python Playground is
Python Playground is a browser-based environment for writing, running, and testing Python without installing a local development setup. Code runs locally in the browser through Pyodide, and the site states that it uses Python 3.12 with the standard library. The editor provides syntax highlighting, automatic indentation, bracket matching, multiple-file organization, light and dark themes, and a debugger with breakpoints, stepping, restart, and variable inspection. Users can install pure-Python wheel packages from PyPI, including NumPy, Pandas, Matplotlib, Plotly, SciPy, scikit-learn, and Requests. CSV, JSON, text, and other data files can be uploaded for Python file operations. Matplotlib and Plotly support interactive charts, while Turtle graphics render in the browser. It runs on the web and as a Chrome extension compatible with Edge and other Chromium browsers. Basic extension work can continue offline after loading.
