Programming: A Starter Project Using MATLAB with Python
or 
Curriculum Module
Created with R2024a. Compatible with R2024a and later releases.
Information
This curriculum module contains interactive MATLAB® live scripts that teach fundamental concepts and basic terminology related to programming computers.
Prerequisite Domain Knowledge
This module assumes familiarity with basic programming concepts such as variables, data types, and functions, structures including arrays and structs, and control flows including if/else as well as how to use them in MATLAB. These ideas are all presented with interactive examples in Fundamentals of Programming, Programming: Organizing Data, Programming: Structuring Code.
Background
You can use these live scripts as demonstrations in lectures, class activities, or interactive assignments outside class. This module explores interactions between systems by using the OpenWeather API and calling into Python from MATLAB. Programming: A Starter Project Using MATLAB with Python covers using the Run Python Code Live Task to run provided Python code, accessing the OpenWeather API to check the weather, extracting useful data from the API call, and using App Designer to create an app with a personalized weather display.
The instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the 
Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.

Getting Started
Accessing the Module
On MATLAB Online:
Use the 
link to download the module. You will be prompted to log in or create a MathWorks account. The project will be loaded, and you will see an app with several navigation options to get you started.
On Desktop:
Download or clone this repository. Open MATLAB, navigate to the folder containing these scripts and double-click on MATLABwithPython.prj. It will add the appropriate files to your MATLAB path and open an app that asks you where you would like to start.
Ensure you have all the required products (listed below) installed. If you need to include a product, add it using the Add-On Explorer. To install an add-on, go to the Home tab and select 
Add-Ons > Get Add-Ons.
Products
MATLAB® is used throughout. Tools from the Symbolic Math Toolbox™ are used to convert between different unit systems in the weather applications.
Scripts
UsingMATLABwithPython.mlx
| Introductory script |
In this script, students will... |
 |
$\bullet$ check that an appropriate version of Python is installed and visible within MATLAB $\bullet$ explore the Run Python Code Live Task $\bullet$ try running Python commands and a Python script from MATLAB |
CheckingTheWeather.mlx
| Investigatory script |
In this script, students will... |
 |
$\bullet$ set up an account with OpenWeather to create your own API key $\bullet$ use existing Python code to make an API call to OpenWeather $\bullet$ use MATLAB to explore the data returned by the API call, including data type conversions and unit conversions |
CreateCurrentWeatherApp.mlx
| Application script |
In this script, students will... |
 |
$\bullet$ use App Designer to build a custom app using the code from CheckingTheWeather.mlx $\bullet$ create callbacks, properties, and functions $\bullet$ design and organize a UI with drag and drop elements $\bullet$ reuse code from CheckingTheWeather in a new context |
Apps
Both of these apps require running Python from MATLAB, as set up in UsingMATLABwithPython and an OpenWeather API key, as set up in CheckingTheWeather.
- CurrentWeatherAppDemo.mlapp shows the results of working through CreateCurrentWeatherApp.
- WeatherDisplay.mlapp shows one elaborated version of the basic current weather app.
