PythonGraphics

The library 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).

This version was modified by me to add useful features. A complete list of changes made from the original is below. Some parts of this README and the wiki in this repository are taken from here and added to/edited by me.

Installation

To install this library, put graphics.py where it can be imported by python. It should work on any platform where Tkinter is available. It works with Python 2 and 3.

Getting Started

Extensive documentation is available in the wiki. Here 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)  # Create a new Graphics Window with a title of "My Circle" and dimensions of 100px by 100px
	c = Circle(Point(50, 50), 10)  # Create a Circle object with a center point at (50, 50) and a radius of 10
	c.draw(win)  # Draw the circle in our window
	win.getMouse()  # Pause program for click in window
	win.close()  # Close the window at the end of the program

main()
