• The shell area: where you can interactively execute Python commands and see the output.
• The toolbar: containing buttons for various operations like running and debugging code.

Writing Your First Python Program in Thonny

To write your first Python program in Thonny, follow these steps:

1. In the editor area, type the following line of code:

• bashCopy code
• print("Hello, World!")

1. Click the Run button in the toolbar (Thonny will first prompt you to save the file).
2. Choose a location to save your Python script and give it a name, such as hello.py.
3. Once the file is saved, Thonny will run the code, and you will see the output “Hello, World!” in the shell area.

Congratulations! You’ve just written and executed your first Python program using Thonny.

Working with Python Libraries and Modules in Thonny

Python offers a wide range of libraries and modules that can help you accomplish various tasks with ease. Thonny makes it easy to work with these libraries and modules. Here’s how:

1. To import a library or module, simply add the import statement at the beginning of your code. For example, to import the math library, type: import math
2. To install a new library, open the “Tools” menu in Thonny’s toolbar, and click “Manage packages.” This will open the package manager, where you can search for and install new libraries. For example, to install the popular requests library, search for "requests" and click "Install."
3. Debugging Python Code in Thonny

Thonny offers powerful debugging tools to help you identify and fix issues in your Python code. Some key debugging features include:

• Step-by-step execution: Thonny allows you to execute your code one line at a time, making it easy to spot issues and understand the flow of your program.
• Breakpoints: You can set breakpoints in your code to pause the execution at specific points, allowing you to examine the state of your program and variables at that point.
• Variable explorer: Thonny’s variable explorer lets you view the values of variables during debugging, helping you identify issues with your code’s logic.

Managing Python Virtual Environments in Thonny

Virtual environments allow you to create isolated environments for your Python projects, ensuring that different projects have their own set of dependencies and packages. Thonny makes it easy to manage virtual environments:

1. To create a new virtual environment, click “File” > “New” > “Python virtual environment.”
2. Choose a location to save the virtual environment and click “Create.”
3. To activate the virtual environment, click “Run” > “Select interpreter” and choose the virtual environment you just created.
4. Using Thonny with Raspberry Pi GPIO

Thonny is compatible with Raspberry Pi’s General Purpose Input/Output (GPIO) pins, allowing you to create projects that interact with various hardware components, such as sensors, LEDs, and motors. To use Thonny with Raspberry Pi GPIO, you will need the RPi.GPIO library:

1. Open Thonny’s package manager and search for “RPi.GPIO.”
2. Install the RPi.GPIO library.
3. Import the library in your Python code using import RPi.GPIO as GPIO.
