cmu-graphics

Desktop CMU Graphics is an offline version of CMU Graphics, a persistent-object graphics package geared towards beginner computer science students. CMU Graphics and its desktop version are maintained by CMU CS Academy, a Carnegie Mellon University project which develops free-to-use middle and high school computer science curriculum.

Desktop CMU Graphics works with Python 3.6-3.11 and is compatible with Replit (see the "Replit" section below). This package, including its documentation, is licensed under the BSD 3-Clause license.

Installation

Choose zip or pip

There are two different ways to install Desktop CMU Graphics on a device:

• (Mac and Windows only) Use the zip file installer that is available for download on the CMU CS Academy website.
• (Mac, Windows, and Linux) Use pip, Python’s built-in package-managing software.

Both methods come with their own advantages and limitations. If you're in doubt about which to choose, the zip file installer is the most likely to succeed. It should work regardless of most restrictions in place on school-distributed devices.

For those using devices with Linux operating systems, or for those who are familiar with the command line/terminal, the pip version of the package offers a larger degree of versatility.

The remainder of these installation instructions are only for the pip version.

Install dependencies

If you're using Windows, you don't need to install any dependencies. Skip ahead to "Install CMU Graphics" below.

If you're using a Mac, install Homebrew.

If you're using a Mac or Linux, install the software packages needed by pycairo. Read their getting started page for instructions.

Install CMU Graphics

Run the following command:

pip install cmu-graphics

Getting Started

To run our graphics framework, include the following line at the top of your Python file:

from cmu_graphics import *

At the end of your Python file, add this line:

cmu_graphics.run()

From there, the syntax for using the graphics package is identical to the online version of the framework. You can find more details about how to use the graphics framework here on our documentation page.
