MicroPython is a reimplementation of Python which is specifically designed to run on computing devices that have very few resources, such as CPU power, RAM and storage. Often when you write scripts in MicroPython you want to make the most of your available resources, and have code run as fast as possible (faster code usually saves power, which is important when running from a battery!) and there are certain ways of writing MicroPython code that are more efficient than others. In this talk I will go over the tricks and techniques for writing fast and efficient Python code in MicroPython. The talk will also include some hardware demos to show off these techniques.
