Sudoku Book Generator

This Python project automates the generation of sudoku puzzle books in PDF format, complete with solutions.

It utilizes code from RutledgePaulV/sudoku-generator to generate the sudoku puzzles themselves, and then formats them into pages before concatenating them into a single PDF document.

How it Works

  1. The sudoku generator algorithm from RutledgePaulV's repository is utilized to generate a given amount of puzzles and solutions, storing them as text files.

  2. The generated puzzles are formatted into 1800×2700px (6×9" 300 dpi) PNG images for pages.

  3. The formatted puzzles and solutions are then combined into a single PDF file.

Usage

To use this sudoku book generator, you can follow these steps:

  1. Clone the repository:

    git clone https://github.com/anna-st-40/sudoku-book-generator

  2. Install the required dependencies:

    pip install -r requirements.txt

  3. Run the Python script to generate your Sudoku book:

    python main.py

  4. The script will ask the number of each difficulty level desired, then will generate the puzzles, pages, and final PDF. These will be in a folder in the same directory as your cloned repository, and will be named according to the time that you ran the script, according to the following convention:

    sudoku_YYYYMMDDHHMMSS

Next steps to do

  • Refactor: PdfMerger is deprecated and will be removed in pypdf 5.0.0. Use PdfWriter instead.
  • Change font sizes and line widths to look nicer
