Part 1: Creating Functions for an Automatic Light Application
Learn how to create functions in the automatic light application.
We'll cover the following
Functions for the automatic light application
We learned how to create functions that can take arguments and return values. Let’s put all of this together and use it in a more realistic application, our automatic light app.
If we again go back to our application for turning on the lights outside our house and focus on the application running on our phone, we’ll see that we have at least two distinct things that we need to do over and over again.
We’ll need to get our current position and calculate our distance to home so we know if it’s time to turn on the lights.
These are two distinct tasks, and they’re very well suited to being packaged up into two different functions, namely, get_current_position
and calculate_distance_to_home
, as shown in the following figure:
