Graphlib topologicalsorter

WebOct 13, 2024 · For this task, Python 3.9 comes with a new module called graphlib that takes care of topological sorting. Besides helping with the total ordering of a set, this module can also be used to consider tasks than enable parallelization when doing advance scheduling. ... from graphlib import TopologicalSorter. ts = TopologicalSorter(dependencies ... WebMar 28, 2024 · In a sense, the TopologicalSorter already is the View/Iterator of the graph (albeit a static one), and the real graph data structure is actually just some dict. (Maybe there is a case for adding a generic stateless graph data structure to graphlib?)...in my code, static_order creates its own view, consumes it, and discards it.

graphlib — Functionality to operate with graph-like structures

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 👍
