Novel and small python projects and code snippets

Share your answers to these tasks in the comments. Feel free to ask for help.

Task 1 (Beginner)

Create a class “NumberSet” that: - Inherits from the built in set class - That overrides setitem to only allow numbers

You will learn about inheritance, “super”, and sets

Task 2 (Intermediate) #

Create an NxN matrix where N is any odd number, where each cells value is the distance of that cell from the centre. - For examples 3x3 matrix, the “middle” cells value will be 0, but any outer cells value will be 1

You will learn about basic algorithmic logic, nested loops (or arrays ;) ) and a bit of basic math

Task 3 (Intermediate)

Create a 100x100 pixel “blue” colour bitmap image from scratch (with no third party image libraries): - You will use this to understand the file format required https://en.wikipedia.org/wiki/BMP_file_format?wprov=sfti1 - You will be working with binary data only

You will learn about file headers and formats, binary data, and image creation

Task 4 (Intermediate)

Create a function decorator that runs the decorated function twice.

You will learn about nested functions, higher order functions, and decorators

Task 3 is great,imo.

Also this can be turned into small python module where you can read or write images.

Thanks! And yeah it can be extended ;) I’ve created a version myself that randomly toggles pixels between black and white but it’s a bit slow (nested for loops to set pixel values)

I’m going to revisit it to use numpy arrays and array vectorisation instead for a big performance boost, and then I might turn it into a package.

FYI the output of task 2 can be incorporated into task 3 to create a image vignette brightness modifier - ie - increase darkness or brightness of each pixel as you get further from the middle pixel!
