Free Python Games Free Python Games is an Apache2 licensed collection of free Python games intended for education and fun. The games are written in simple Python code and designed for experimentation and changes. Simplified versions of several classic arcade games are included. Python is one of the top-five most popular programming languages in the world and available for free from Python.org. Python includes an extensive Standard Library distributed with your installation. The Standard Library has a module called Turtle which is a popular way to introduce programming to kids. All of the games in Free Python Games are implemented using Python and its Turtle module. The games run anywhere Python can be installed which includes desktop computers running Windows, Mac OS, or Linux and older or low-power hardware such as the Raspberry Pi. Each game is entirely independent from the others and includes comments. 1) Features Fun to play! Simple Python code Easy to install Designed for education Depends only on the Python Standard Library Developed on Python 3.7 Tested on CPython 2.7, 3.4, 3.5, 3.6, and 3.7 Tested on Windows, Mac OS X, Raspbian (Raspberry Pi), and Linux Tested using Travis CI and AppVeyor CI 2) Quickstart Installing Free Python Games is simple with pip: $ python3 -m pip install freegames Free Python Games supports a command-line interface (CLI). Help for the CLI is available using: $ python3 -m freegames --help The CLI supports three commands: list, copy, and show. For a list of all games run: $ python3 -m freegames list Any of the listed games may be played by executing the Python module from the command- line. To reference the Python module, combine “freegames” with the name of the game. For example, to play the “snake” game run: $ python3 -m freegames.snake Games can be modified by copying their source code. The copy command will create a Python file in your local directory which you can edit. For example, to copy and play the “snake” game run: $ python3 -m freegames copy snake $ python3 snake.py Python includes a built-in text editor named IDLE which can also execute Python code. To launch the editor and make changes to the “snake” game run: $ python3 -m idlelib.idle snake.py You can also access documentation in the interpreter with Python’s built-in help function: >>> import freegames >>> help(freegames) 2. Games If you have have the look at the index we are going to code 15 python based games so lets start with the game number one 1) Snake classic arcade game. Use the arrow keys to navigate and eat the green food. Each time the food is consumed, the snake grows one segment longer. Avoid eating yourself or going out of bounds!

Click to mark the start of a shape and click again to mark its end. Different shapes and colors can be selected using the keyboard.
