Python SDK Examples

Each example folder contains runnable versions:

• sync.py (public sync surface: Codex)
• async.py (public async surface: AsyncCodex)

All examples intentionally use only public SDK exports from codex_app_server.

Prerequisites

• Python >=3.10
• Install SDK dependencies for the same Python interpreter you will use to run examples

Recommended setup (from sdk/python):

python -m venv .venv
source .venv/bin/activate
python -m pip install -U pip
python -m pip install -e .

Run examples

From sdk/python:

python examples/<example-folder>/sync.py
python examples/<example-folder>/async.py

The examples bootstrap local imports from sdk/python/src automatically, so no pip install -e . step is required to run them from this repository checkout. The only required install step is dependencies for your active interpreter.

Recommended first run

python examples/01_quickstart_constructor/sync.py
python examples/01_quickstart_constructor/async.py
