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 <https://processing.org/>_ — learning to code in a visual context — with Python's readability to make programming more accessible to beginners, educators, and artists.

To report a bug / make a feature request use the issues page <https://github.com/p5py/p5/issues> in this repository. You can also use the discourse platform <https://discourse.processing.org/c/p5py/27> to ask/discuss anything related to p5py.

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:

.. code:: python

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
