Graphics with NumPy
In this tutorial you find NumPy exercises that create images.
It is meant as a gentle introduction to NumPy. It assumes that you have made your first steps with Python already. To get the best out of it, put it into practice immediately:
paint things – create art – have fun!
Installation
If you are using the Anaconda distribution, you should have all necessary libraries already.
Otherwise, download or clone the git repository github.com/krother/generative_art and install the libraries using pip:
:::bash
pip install -r requirements.txt
Next, try the examples and challenges.
