About Python Compiler

Execute Python 3.11 code via Pyodide WebAssembly engine.

Important limitations

This isolated browser runtime supports small Python and standard-library examples. Program access to site storage, outbound network and external packages is blocked. Pinned runtime files download before execution. Variables persist between nearby runs. Reset engine, Stop or closing the tool clears them. The engine also resets after five idle minutes or unresponsive idle background code; background-tab timers may delay cleanup until the tab is active again.

Use these browser runtimes for short examples and learning. They are not full local development environments. Check runtime limitations before pasting project code, and never include credentials or code you do not trust.
