p5.py

A p5.js clone written entirely in Python aiming to support the same featureset. It is currently a work in progress, see TODO.md for more details about the current progress.

How to install?

As of writing ther is no pip package available, instead you can clone this repository and take a look at the examples section. There is no need to include the p5.js package in your $PATH environment variable. To start out just run: python test.py It will search in the current directory for the p5.py package and the package will run the sketch.

Example

The following example will draw a rotating ball which changes color

from p5 import *                # Import all functions from the p5.py package
import math

def setup():                    # The starting point of the sketch
    CreateWindow(640, 480)      # Create the display window
    background(name="white")    # Set the background to white
    caption("hey!")             # Change the title of the window

col = 0
x,y = 0,0
n = True

def draw():                     # The draw function is continuously called to draw each frame
    if n: clear()
    global col, x, y
    fill(math.cos(0.2*col)*255, math.sin(0.2*col)*255, math.tan(0.2*col)*255)   # Set the color of shapes
    translate(math.cos(x)*100+200+math.sin(y-0.2)*25,
        math.atan(y)*100 + 100 + math.sin(x)*50+math.cos(y+3)*50)               # Translate following objects
    rotate(math.cos(y)*TAU)                                                     # Rotate objects
    ellipse(0, 0, abs(math.cos(y)*50)+20, abs(math.sin(x)*30)+20)               # Draw an elllips
    x += 0.05; y += 0.05; col += 0.1                                            # Increase values in loop

def KeyPressed():              # This function is called when a key is pressed
    global n
    if n: n = False
    else: n = True

Result:
