A sudoku creator and solver in python that is able to create sudokus in machine and human-readable format.
There are no external dependencies apart from python3.

./sungoku.py create --number 10 --min-hints 30

Generate a sudoku in human-readable format:
./sungoku.py create --pretty
# 4 | 6 1 | 9
# | | 8
# 1 6 | 8 7 |
# - - - + - - - + - - -
# | 4 |
# 6 1 | 2 |
# 2 9 | 7 | 3
# - - - + - - - + - - -
# | | 1
# 7 | 1 | 3 2
# 3 | 8 | 7 6
#
# Number of hints: 26
# Difficulty: MEDIUM
Solve a list of sudokus from a file and check if it is minimal and a unique solution exists:
./sungoku.py solve -a < some_file.csv
Try to solve sudokus from some other dodgy text-based file format:
grep -o "[0-9\._-]\{81\}" some_file.txt | xargs -n1 ./sungoku.py solve -i -p -s
Do a whole Sunday afternoon worth of sudokus within a matter of seconds, so you can go back and watch your favourite sitcom:
./sungoku.py create -m 28 -n 8 | ./sungoku.py solve -p > /dev/null
