Python Processing Starter

This project provides a small Processing-like API on top of Pygame, using Python-style naming. It is designed for quick visual programming, classroom demos, and beginner-friendly sketch workflows.

Project Goal

The goal is to let you write simple sketches with minimal setup:

• define setup() for one-time initialization
• define draw() for frame-by-frame rendering
• call run() to start the sketch loop

You can use functions like size(), background(), circle(), text(), image(), and input callbacks.

Preparation

1. Have Python!
2. Install Pygame using pip: pip install pygame

Create Your First Sketch

Create a file like my_sketch.py:

from processing import *

x = 0


def setup():
    size(800, 500)
    frame_rate(60)
    title("My First Sketch")


def draw():
    global x
    background(245)
    fill(80, 170, 255)
    no_stroke()
    circle(x, 250, 40)
    x = (x + 2) % width


run()

Run it with:

python my_sketch.py

API Documentation

See api.md for the full English API reference, including:

• public constants
• public runtime variables
• public functions
• optional callback handlers

Notes

• Function and variable names follow snake_case.
• ESC closes the sketch window.
• The runtime supports both static and interactive sketch modes.
