p5

p5 is a Python library that provides high level drawing functionality to help you quickly create simulations and interactive art using Python. It combines the core ideas of Processing — learning to code in a visual context — with Python's readability to make programming more accessible to beginners, educators, and artists.

Example

p5 programs are called "sketches" and are run as any other Python program. The sketch above, for instance, draws a circle at the mouse location that gets a random reddish color when the mouse is pressed and is white otherwise; the size of the circle is chosen randomly. The Python code for the sketch looks like:

from p5 import *

def setup():
    size(640, 360)
    no_stroke()
    background(204)

def draw():
    if mouse_is_pressed:
        fill(random_uniform(255), random_uniform(127), random_uniform(51), 127)
    else:
        fill(255, 15)

    circle_size = random_uniform(low=10, high=80)

    circle((mouse_x, mouse_y), circle_size)

def key_pressed(event):
    background(204)

# p5 supports different backends to render sketches,
# "vispy" for both 2D and 3D sketches & "skia" for 2D sketches
# use "skia" for better 2D experience
# Default renderer is set to "vispy"
run(renderer="vispy") # "skia" is still in beta
