aioturtle

Extension of the python standard library turtle module to move turtles asynchronously using the asyncio module and the new async/await syntax in python 3.5.

The purpose of this package is to provide a toy enviornment to learn and play with the asyncio library and new python coroutine syntax. While this can be easily achieved by creating coroutines that simply call asyncio.sleep(...) and print messages to the screen, I find that being able to watch animated turtles move about the screen is a more satisfying way to learn asyncio using a toy model.

Introduction

Disclaimer

This package essentially ignores the TCL/TK GUI event loop and treats the TK Canvas object as something that updates and draws effectively instantaneously. The "IO" delays from the moving turtles are created artificially by await asyncio.sleep(...) statements within the turtle movement coroutines, although canvas delays may contribute to the actual wall clock times elapsed between moves.

All GUI functionality is disabled in the turtle classes provided in this package. Turtles can be managed interactively by the TurtlePrompt class or by user created command line interfaces.
