    1 - Introduction to Python

    Python is a widely-used programming language known for its simplicity and readability. It was created by Guido van Rossum and first released in 1991. Python has become one of the most popular programming languages in the world, used in various fields such as web development, data analysis, artificial intelligence, and more. In fact, Python is often the first language taught in schools and universities due to its beginner-friendly syntax.

    In this lesson, you will learn the basics of Python and get familiar with the Micro:bit Python editor. The Micro:bit is a small, programmable device that can be used to create exciting projects and learn programming concepts. By the end of this lesson, you'll have a solid foundation in Python and be ready to explore more advanced topics.

    Python has a large community of developers, which means you'll find plenty of resources and support as you learn. With Python, you can build websites, create games, analyze data, and even program robots. Let's get started on your Python journey!

    You do not need to have a physical microbit to do this course because you can use the virtual microbit in the editor. But if you do have a physical microbit you can load your code onto it for each of the projects. 


    2 - Access the Micro:bit Python Editor

    Visit the Micro:bit Python editor by clicking here. This will open up a new browser tab and show the Python code editor where you will write and test your Python code throughout this course.

    When you start a new project, you might see some default code like this:

    # Imports go at the top
    from microbit import *
    
    # Code in a 'while True:' loop repeats forever
    while True:
        display.show(Image.HEART)
        sleep(1000)
        display.scroll('Hello')

    Keep the first line of the code, which is:

    from microbit import *

    This line is important because it imports all the necessary functions and classes from the Micro:bit library, allowing you to use them in your code. Without this line, you won't be able to access the Micro:bit's features like the display or buttons.

    Delete the rest of the code before moving to the next step.


    3 - Python Indentation

    Python has a simple syntax that makes it easy to read and write.

    Python uses indentation to define code blocks. Each level of indentation is represented by 4 spaces or a tab. Here's an example:

    x = 5
    
    if x > 0:
        display.scroll("x is positive") # this line is indented
    
    y = -3 # this line is NOT indented
    
    if y < 0:
        display.scroll("y is negative")

    Notice how the display.scroll statements are indented to show that they're inside the if blocks. The next lines of code after the first if block are not indented, indicating that they are not inside the first if block.

    You don't need to add this code to your project, just understand how the code indentation works.

    4 - Python Comments

    Comments are an essential part of any programming language. They allow you to add notes and explanations to your code. In Python, you can create comments using the # symbol. Any text after the # symbol on the same line will be considered a comment and ignored by the interpreter.

    When we say 'ignored by the interpreter', it means that the Python interpreter, which reads and executes your code, will not consider the text after the # symbol as part of the code. It will treat it as a note or explanation, and it won't affect the execution of your program.

    Here's an example:

    # This is a comment
    print("Hello, World!")  # This is an inline comment
    You don't need to add this code to your project, just understand how adding comments works.

    5 - Write Your First Python Program

    Now, let's write your first Python program. In the Micro:bit Python editor, type the following new code:

    from microbit import *
    
    display.scroll("Hello, World!")

    Click the 'Run' button to see the output of your program. You should see the text "Hello, World!" displayed in the output area.
