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. WebGraphs Topologicalsorter Done Overview: The done()method of the TopologicalSorterclass marks a node of a Directed Acyclic Graph(DAG) as visited. As all the nodes of the DAG are marked as visited, a TopologicalSorter instance becomes inactive. For example, as a workflow gets complete the workflow becomes inactive. Example:
