Built on top on Python's asynchronous I/O support introduced in PEP 3156, it provides an API based on coroutines, making it easy to write highly concurrent applications.
Installation is as simple as
pip install websockets. It requires Python ≥
3.4 or Python 3.3 with the
asyncio module, which is available with
install asyncio or in the Tulip repository.
