[docs] [issue42201] Priority queue realization issue

New submission from Даниил Ляхов : In Priority queue realization in docs https://docs.python.org/3/library/heapq.html there is no appointments that priority can be equal and the task can have different type. For example, if you store number of graph node in your priority queue, than it is possible to get "TypeError: '<' not supported between instances of 'int' and 'str'", because inside heappop there is comparison between elements, and if the fist elements the same, than it compare tasks, which can be tagged as removed and has '<removed-task>' value as opposed to number of node, which is int. ---------- assignee: docs@python components: Documentation messages: 379922 nosy: docs@python, dupeljan priority: normal severity: normal status: open title: Priority queue realization issue type: behavior versions: Python 3.9 _______________________________________ Python tracker https://bugs.python.org/issue42201 _______________________________________
