Local only
Run Python code in a browser-based runtime and review output after each run
Python via Pyodide with popular compatible libraries and modules
Use compatible packages such as pandas, numpy, matplotlib, and plotly when supported
Start writing and running Python code without local setup
Create and manage multiple Python files in your environment
Run Python code on any device with a modern web browser
Our online Python compiler uses WebAssembly technology to run Python code directly in your browser. Use syntax highlighting, error display, and browser-based output without setting up a local Python environment.
Use compatible Python packages for data examples, charts, and numerical work in the browser. Package support depends on the Pyodide runtime and browser environment.
Use browser-compatible Python libraries for data examples, charts, numerical work, and classroom exercises without setting up a local virtual environment.
Many pure Python packages can run in the browser runtime when their dependencies are compatible. This works well for learning examples, utility code, parsers, helpers, and package-compatible scripts.
Python Playground also supports browser-rendered turtle graphics for beginner-friendly visual examples. Use Python Turtle Online when your code needs drawing, movement, colors, fills, or text output.
This is a browser Python runtime, not a full local operating system. Packages that need unsupported native binaries, system services, desktop windows, or unrestricted local file access may not run in the browser.
Perfect for students and educators learning Python programming concepts
Try browser-compatible data examples with packages such as pandas, numpy, and matplotlib
Test sorting algorithms and solve competitive programming challenges
Isolate problematic code sections and test fixes in a controlled environment
Quickly prototype application logic and validate concepts
Prototype backend-style logic and browser-compatible HTTP requests before moving code into production
Our Online Python Compiler is a browser-based Python runner that lets you write and execute Python code without local setup. It runs Python through Pyodide/WebAssembly and is designed for snippets, scripts, compatible packages, files, plots, and learning examples.
Use it when you want to run Python quickly without installing a local environment. It is useful for learning, prototyping, data analysis examples, package-compatible snippets, plots, and focused browser-based Python workflows.
You can use many browser-compatible Python packages, including popular Pyodide packages such as numpy, pandas, matplotlib, scipy, and plotly. Pure Python packages often work, but packages that require unsupported native system dependencies may not run in the browser runtime.
Your Python code runs locally in your browser by default using WebAssembly technology. If you use Pro cloud sync, selected playground files, package settings, metadata, and uploads are stored in cloud infrastructure for sync and backups.
Once loaded, the compiler works offline for basic local Python programming. You can write, edit, and run code without internet. Installing new packages, signing in, upgrading to Pro, and syncing cloud playgrounds require an internet connection.
