Look inside

In this liveProject, you’ll use Python to build a nonogram puzzle generator that creates a printable puzzle pack from the command line. Nonograms are puzzles that reveal an image on a grid, based on numbers along the grid’s edge. Most programmatic implementations solve nonograms, but yours will generate them. To do this, you’ll code your script, relying on two essential data structures: the pandas DataFrame and the NumPy array. You’ll also experiment with image libraries including Pillow and pixelate, and gain a better understanding of basic image processing concepts.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

  • Converting between data structures
  • Installing third-party libraries
  • Running a Python script from the command line

you will learn

In this liveProject, you’ll build a script that will generate a PDF file for a nonogram puzzle from an image. The skills you’ll learn throughout this project will be directly applicable to your job as a software developer, analyst, or data scientist.

  • Manipulating image files
  • Pillow library
  • pixelate library
  • regular expressions
  • Styling a DataFrame
  • Basic HTML and CSS
  • Exporting a table as an image file
  • Generating PDF files
  • Converting between data structures
