How to use the yappi.yappi.YFuncStats.get function in yappi

with this approach is YFuncStats has an internal list which complicates:
        - delete() operation because list deletions are O(n)
        - sort() and pop() operations currently work on sorted list and they hold the
          list as sorted.
    To preserve above behaviour and have a delete() method, we can use an OrderedDict()
    maybe, but simply that is not worth the effort for an extra filter() call. Maybe
    in the future.
    """
    tag = filter.get('tag', tag)
    ctx_id = filter.get('ctx_id', tag)

    # multiple invocation pause/resume is allowed. This is needed because
    # not only get() is executed here.
    _yappi._pause()
    try:
        stats = YFuncStats().get(filter=filter, filter_callback=filter_callback)
    finally:
        _yappi._resume()
    return stats
