Block until a container stops, then return its exit code. Similar to
        the ``docker wait`` command.

        Args:
            container (str or dict): The container to wait on. If a dict, the
                ``Id`` key is used.
            timeout (int): Request timeout
            condition (str): Wait until a container state reaches the given
                condition, either ``not-running`` (default), ``next-exit``,
                or ``removed``

        Returns:
            (dict): The API's response as a Python dictionary, including
                the container's exit code under the ``StatusCode`` attribute.

        Raises:
            :py:class:`requests.exceptions.ReadTimeout`
                If the timeout is exceeded.
            :py:class:`docker.errors.APIError`
                If the server returns an error.
