Python client for the etcd API v3, supported under python 2.7, 3.4 and 3.5.

**Warning: the API is mostly stable, but may change in the future**

If you're interested in using this library, please get involved.

Basic usage:

.. code-block:: python

    import etcd3

    etcd = etcd3.client()

    etcd.get('foo')
    etcd.put('bar', 'doot')
    etcd.delete('bar')

    # locks
    lock = etcd.lock('thing')
    # do something
    lock.release()

    with etcd.lock('doot-machine') as lock:
        # do something

    # transactions
    etcd.transaction(
        compare=[
            etcd.transactions.value('/doot/testing') == 'doot',
            etcd.transactions.version('/doot/testing') > 0,
        ],
        success=[
            etcd.transactions.put('/doot/testing', 'success'),
        ],
        failure=[
            etcd.transactions.put('/doot/testing', 'failure'),
        ]
    )

    # watch key
    watch_count = 0
    events_iterator, cancel = etcd.watch("/doot/watch")
    for event in events_iterator:
        print(event)
        watch_count += 1
        if watch_count > 10:
            cancel()

    # watch prefix
    watch_count = 0
    events_iterator, cancel = etcd.watch_prefix("/doot/watch/prefix/")
    for event in events_iterator:
        print(event)
        watch_count += 1
        if watch_count > 10:
            cancel()

    # recieve watch events via callback function
    def watch_callback(event):
        print(event)

    watch_id = etcd.add_watch_callback("/anotherkey", watch_callback)

    # cancel watch
    etcd.cancel_watch(watch_id)
