python sudoku generator and solver
Project description
A Sudoku generator and solver
This is a Sudoku game written in python, default to use Wave Function Collapse method.
A puzzle can be generated by following function with a mask rate.
Install
pip install sudokum
Generation
A sudoku can be generated with a mask_rate
. A full solution is generated when passing mask_rate=0
.
import sudokum
g = sudokum.generate(mask_rate=0.7)
print(g)
"""
[[1 0 0 5 0 0 0 0 3]
[0 3 7 0 0 1 0 0 4]
[0 0 0 0 0 2 0 0 0]
[0 0 0 0 9 4 0 0 0]
[0 0 4 0 0 0 0 3 2]
[0 0 0 3 2 5 0 0 0]
[0 0 0 0 0 0 2 0 0]
[7 4 0 0 0 0 0 0 0]
[8 0 0 0 0 3 1 0 0]]
"""
To visualize the generating procedure, I have made a GUI for animate Wave Function Collapse in sudoku generation.
import sudokum
sudokum.display_wfc()
Or you can get you hand on it by running following code.
import sudokum
sudokum.display_wfc(human=True)
Solving
By using solver()
function, it tries to solve the puzzle.
import sudokum
g = sudokum.generate(mask_rate=0.7)
s = sudokum.solve(g)
print(s)
"""
[[1 2 8 5 4 7 6 9 3]
[6 3 7 9 8 1 5 2 4]
[4 9 5 6 3 2 7 1 8]
[2 1 3 7 9 4 8 5 6]
[5 7 4 1 6 8 9 3 2]
[9 8 6 3 2 5 4 7 1]
[3 5 1 4 7 6 2 8 9]
[7 4 2 8 1 9 3 6 5]
[8 6 9 2 5 3 1 4 7]]
"""
A solving max try number can set as following:
import sudokum
s = sudokum.solve(g, max_try=3)
Manually check solution
If you have your own solution, you can validate it by following function:
import sudokum
ok, position_of_problems = sudokum.check(g)
More Example
More use cases can be found in my test files.
