I made a small program in Matlab a few months ago that drew the Mandelbrot set. It took about 15 seconds. To make 5 frames.Thanks for the memory. I wrote several such programs in the 80s and had great fun watching them evolve on the screen. It took about 15 minutes per frame, and it was one of the rare cases when slower computers were more fun than fast ones.
A quick google search of "mandelbrot python" returned many hits.
