Graphlib topologicalsorter
WebIn the general case, the steps required to perform the sorting of a given graph are as follows: Create an instance of the :class:`TopologicalSorter` with an optional initial graph. Add additional nodes to the graph. Call :meth:`~TopologicalSorter.prepare` on the graph. WebYou are right in stating that many sources ignore that their can be many ordering for a given graph - like the Python 3.9 graphlib documentations own example that I used. It's usually ignored in introducing t-sort, but when graph lib has task support, it needs to be mentioned. Networkx? Thanks for the excellent feedback by the way 👍
