Variables in programming act like placeholders for data. In the last section, you crunched some numbers. But what if we want to use those numbers again later? Doing the math all over again doesn't make much sense.

To remember a value for later, we give it a name by using a variable. The equals sign `=` lets us set a value for that variable. For instance, you can set the variable `year` to the value `2024`, and from there, you can display it or do more math with it.

# Create a variable
year = 2024
# Output its value
print(year)
# Perform an addition
print(year + 10)

## Task

We're in the seventh chapter of the course. Set up a variable called `chapter` and give it the value `7`.

Python is an interpreted high-level general-purpose programming language. Unlike HTML, CSS, and JavaScript, which are primarily used for web development, Python is versatile and can be used in various fields, including software development, data science, and back-end development. In this course, you'll explore the core aspects of Python, and by the end, you'll be crafting your own functions!

In this section, you'll dive into the basics of Python, familiarize yourself with your workspace, tackle simple math operations, and display your results.

Here, you'll learn how to store items like numbers and text in computer memory, recalling them by name. You'll also get a taste of text manipulation in Python.

Here, you'll delve into the boolean data type and discover its role in creating programs that respond to specific conditions.

Continuing with data types, this section will teach you how to group varied attributes within a single variable using lists, tuples, and the dictionaries.

In this part, you'll master the art of writing loops in Python – essential constructs for iterating over lists, tuples, dictionaries, and even future dataframes.

To wrap up our introductory course, you'll explore some built-in functions and then embark on creating your very own!
