PyStage - Scratch Like Python Programming

PyStage bridges the gap between Scratch and Python. This module implements all code blocks as available in scratch. With the PyStage command line converter Scratch projects can be easily transferred to Python executable Code. To run your game in Python, PyStage uses PyGame.

Demo

Consider the following code. It defines a stage and a sprite on the stage. The functions are code blocks that are associated with events (i.e. connected to a hat block in Scratch) via the corresponding methods.

from pystage.en import Stage

stage = Stage()
stage.add_backdrop("grid")
zombie = stage.add_a_sprite()

def doit(zombie):
    zombie.say("Hello pyStage!")
    for i in range(4):
        zombie.move(10)
        zombie.wait(1)
        zombie.think("This is awesome!")
        zombie.turn_left(90)
        zombie.wait(1)
        zombie.think("")
    zombie.say("Move me around with WASD.")

zombie.when_program_starts(doit)

def right(zombie):
    zombie.change_x_by(10)

def left(zombie):
    zombie.change_x_by(-10)

def up(zombie):
    zombie.change_y_by(10)

def down(zombie):
    zombie.change_y_by(-10)

zombie.when_key_pressed("d", right)
zombie.when_key_pressed("a", left)
zombie.when_key_pressed("w", up)
zombie.when_key_pressed("s", down)

stage.play()

And here is the result:

Goals

  • Export your Scratch project to real executable Python code!
  • Helping coding beginners to learn Python “by Scratch”.
  • Implementation of scratch blocks in several languages (ideal for kids). As of now en and de.
