A CLI tool for solving sudoku puzzles.
pip install sudoku-cli
The help page for the sudoku command is a good overview:
Usage: sudoku [OPTIONS] INPUT_FILE
A command line tool for taking an input file encoding sudoku problems and
writing their solutions to stdout.
The input file consists of one sudoku problem per line, where each line is
a string of integers in the range 0-9. A 0 denotes an empty location while
all the other digits are filled cells. This string represents a walk
through the grid from top to bottom and left to right.
By default it exits with a message after encountering either an invalid
problem or an unsolvable problem.
Options:
-s, --size INTEGER Size of the encoded sudoku problems. Defaults to 9.
-i, --ignore Silently ignores all errors. Writes blank lines for
unworkable problems.
--help Show this message and exit.
The input file format is described above in the help page.
So this board:
|0 9 0| |0,0,0| |0,0,6| |0 0 0| |9,6,0| |4,8,5| |0 0 0| |5,8,1| |0,0,0| |0,0,4| |0,0,0| |0,0,0| |5,1,7| |2,0,0| |9,0,0| |6,0,2| |0,0,0| |3,7,0| |1,0,0| |8,0,4| |0,2,0| |7,0,6| |0,0,0| |8,1,0| |3,0,0| |0,9,0| |0,0,0|
Would be encoded by this string:
090000006000960485000581000004000000517200900602000370100804020706000810300090000
