I made a sudoku solving code in python, closely following the solution given on GeeksForGeeks, but my code runs really slowly, albeit producing correct results.

It took over 2 minutes to run, whereas the GeeksForGeeks code took under a second to solve 2 such Sudokus:

QUESTION

How to set multiple attributes on the same element

Asked 2022-Jan-20 at 15:07

I am creating a sudoku gameboard and I need to draw some lines to divide the 3x3 boxes. The board is made out of buttons, so what I am trying to do is change the border color from the buttons on the 3rd and 6th column, & line.

The problem I am facing is that I can't add on a button 2 borders: right and bottom. The Js code only adds one attribute at a time, using elem.setAttribute. So I tried a function that supposedly lets you add more than 1 attribute, but it doesn't seem to work.

Where is the bug?

If you only use setAttribute for styling, you could fix it like this:

You are suffering confusion between "generator" and "container". Consult type( ... ) to tell the difference between them.

Python generators are "lazy", for excellent technical reasons. Sometimes we can get away with just evaluating the first K items of an infinite generator.

In your method you want everything greedily pulled out, and then stored in a container. The conventional way to phrase this is to wrap map with list:

How to solve Sudoku with Python?

Asked 2022-Jan-09 at 15:13

I was wondering how to solve this Sudoku board in Python using Human input and Computer solving. I have a Human and Computer solve def. I tried using rows and columns to solve and it just wouldn't print the results on the board every time it would work. I tried doing these using things such as for 'i in range'. But when I would run the program it would be working but not printing the results each time it was solving it. Thank you!

...

ANSWER

Answered 2022-Jan-09 at 15:13

You would solve it programmatically the same way you would solve it as an intelligent human.

Have a set of discovery rules that you apply to groups (rows, columns, or 3-by-3s) to eliminate possibilities, or select values where there is but one possibility.

For example, consider the first three rows in the first puzzle:

As stated by Craig there is currently no chance to reproduce your program so I have to make some assumptions. I am assuming that the s.Add() in your first code sample actually uses one \t more than shown in your snippet. I would argue that at least the parantheses within the list comprehension are not set properly. So my comprehensed list is referring to an original code looking like:

QUESTION

Python: why does this variable value change?

Asked 2022-Jan-03 at 19:00

I am learning recursion and came through this code (not mine: https://github.com/kying18/sudoku) and cannot figure out why the variable example_board changes value. It is never addressed again and no other variable is linked to it? I tested it and it does!

Here is the condensed version of the relevant code:

...

ANSWER

Answered 2022-Jan-03 at 18:56

When printing in the line: "print(solve_sudoku(example_board))" example_board is passed into solve_sodoku. The solve_sodoku function then changes it values in this line: "puzzle[row][col] = guess" as puzzle is referencing the example_board variable and one of its value is being changed to guess.

Hope this helped!
