# Python Console

Embedded interactive Python REPL in a terminal widget.

```

**Tags:** `ui`

Pairs the TerminalEmulator widget with PyConsoleNode -- an in-process Python
interpreter. Unlike the bash terminal demo (which needs a real PTY and only runs
on desktop), this console runs *inside* the app's own interpreter, so it works
identically on desktop and in the browser via Pyodide. It also shares the live
program state: the namespace below exposes the scene tree so you can poke at it.

Try:
  - 2 ** 100
  - import math; math.tau
  - [n.name for n in tree.root.children]
  - help(str)        (then type q to leave the pager-free help)

Controls:
  - Click the terminal to focus, type to interact
  - Left/Right/Home/End edit the line; Up/Down recall history
  - Ctrl+C cancels the current line; Ctrl+D (empty line) or exit() closes it

Run: uv run python examples/features/ui/python_console.py
