But that does seem to be the plan that TopographicalSorter provides: ```python graph = {"go": {"a"}, "a": {"b", "c"}, "b": {"c", "d"}}

ts = TopologicalSorter(graph) ts.prepare() while ts.is_active(): nodes = ts.get_ready() print(nodes) ts.done(*nodes) Outputs: ('c', 'd') ('b',) ('a',) ('go',) Also:python graph = {"go": {"d", "e", "f"}, "d": {"b", "c"}, "b": {"c"}}

ts = TopologicalSorter(graph) ts.prepare() while ts.is_active(): nodes = ts.get_ready() print(nodes) ts.done(nodes) Gives: ('e', 'f', 'c') ('b',) ('d',) ('go',) `` I'm confident thatTopologicalSorteris the way to do this. I think I need to rewrite my code to call it once to get that plan, thenawait asyncio.gather(nodes)` in turn to execute it.
