all set , all functions work well

graphs/dijkstra.py

ZeroDayOwl · 2022-10-19T10:29:00Z

@AtulRajput01 check pre-commit details and fix the issues.

cclauss · 2022-10-19T11:34:08Z

Instead of deleting someone else's work, let's move this to a separate file graphs/dijkstra_alternate.py and make sure that naming, tests, type hints are in compliance with https://github.com/TheAlgorithms/Python/blob/master/CONTRIBUTING.md

graphs/dijkstra.py:6:10: N802 function name 'printSolution' should be lowercase
graphs/dijkstra.py:11:10: N802 function name 'minDistance' should be lowercase
graphs/dijkstra.py:11:34: N803 argument name 'sptSet' should be lowercase
graphs/dijkstra.py:13:9: A001 variable "min" is shadowing a python builtin
graphs/dijkstra.py:16:44: E712 comparison to False should be 'if cond is False:' or 'if not cond:'
graphs/dijkstra.py:17:17: A001 variable "min" is shadowing a python builtin
graphs/dijkstra.py:26:10: N806 variable 'sptSet' in function should be lowercase
graphs/dijkstra.py:28:13: B007 Loop control variable 'cout' not used within the loop body. If this is intended, start the name with an underscore.
graphs/dijkstra.py:36:35: E712 comparison to False should be 'if cond is False:' or 'if not cond:'

AtulRajput01 · 2022-10-19T18:04:49Z

done sir

cclauss

According to CONTRBUTING.md there needs to be at least one algorithmic function that takes in one or more parameters and returns one or more values. Algorithmic functions should not print().

okay sir ,i understood very well.

Abinashbunty

In line 30, during function call, it should be self.minimum_distance
All dist should be distances ~~or vice versa~~.
All sptset should be spt_set ~~or vice versa~~ or a more self-documenting name.
printsolution should be print_solution ~~or vice versa.~~
Include doctests.
Provide some comments in algorithm execution.

Abinashbunty · 2022-10-19T19:51:30Z

A general advice is to execute the code online/locally to fix the compilation(interpreter) errors. 👍🏻

it's working on my machine as well, then why pre-commit failure accur

Moreover, check my comment above which Christian has edited. Use distances, spt_set and print_solution.

for more information, see https://pre-commit.ci

cclauss · 2022-10-19T21:56:19Z

OK. I changed the filename, used self-documenting names for functions and variables, added type hints, and docstrings with doctests.

I still have no clue what a better name for sptset would be except perhaps visited.

Abinashbunty · 2022-10-19T22:10:10Z

@cclauss visited seems the only logical variable name for sptset.

Did you run the tests as mentioned in the contributing guideline?

AtulRajput01 · 2022-10-20T07:42:05Z

ok
