Brief Description

Graphics.py is a simple object oriented graphics library. It is designed to make it very easy for novice programmers to experiment with computer graphics in an object oriented fashion. It is written by John Zelle for use with the book "Python Programming: An Introduction to Computer Science" (Franklin, Beedle & Associates).

The package is a wrapper around Tkinter and should run on any platform where Tkinter is available.

There are two kinds of objects in the library. The GraphWin class implements a window where drawing can be done and various GraphicsObjects are provided that can be drawn into a GraphWin.

Graphics.py V5 is an open-source software released under the terms of the GPL (http://www.gnu.org/licenses/gpl.html).

Simple Example Program

Here is a simple example. It is a complete program to draw a circle of radius 10 centered in a 100x100 window:

from graphics import * def main(): win = GraphWin("My Circle", 100, 100) c = Circle(Point(50,50), 10) c.draw(win) win.getMouse() # Pause to view result win.close() # Close window when done main()

Display the graphic.py version

import graphics as gr print(f'graphics.py version is {gr.__version__}')

Graphics.py is Missing a Button

How would you create a button? You would want to click on it and have some action performed. See the following code for a hint.

# Create a rectangle Or other shape. Was the mouse click inside it? while True: mp = win.checkMouse() # mouse click location (if any) if mp is not None: # was their a mouse click? x = mp.getX() # mouse click x coordinate y = mp.getY() # mouse click y coordinate if x > 10 and x < 50 and y > 10 and y < 50: Perform Some Action
