Free Online Python Compiler and Playground
Write, run, and debug Python 3 in your browser. No installation required.
Edit the sample project above or replace it with your own Python code, then press Run. The Python 3 interpreter runs in your browser through WebAssembly, so you don't need to install Python or create an account.
Use it to test a short snippet, trace an error, or work across a few Python files without setting up a local development environment.
How to use the online Python compiler
- Edit
main.py, or add another.pyfile for a multi-file program. - Press Run to execute the code and read its printed output or traceback in the console.
- Keep experimenting. Your code is saved in this browser until you reset it or clear your local site data.
What this Python playground supports
- Python 3 in the browser. Run code without downloading Python or configuring an IDE.
- Multi-file programs. Work with up to five Python files and import them from
main.py. - Supported packages. Import packages available in the Pyodide runtime; the editor loads supported dependencies when you run the code.
- Local autosave. Leave the page and come back without losing the code saved in this browser.
Learn Python by writing code
A playground is useful when you know what you want to test. For a structured introduction to variables, functions, loops, data structures, testing, and debugging, work through the hands-on beginner course.
