Introduction
Machine learning for kids: Welcome to this tutorial on Python Variables! Variables are the backbone of any programming language, serving as containers where we store our data. They’re like little boxes where we can put things for use later.
Who Is This For?
Grade: 6th to 10th
This tutorial is designed for students in grades 6 through 10. Whether you’re completely new to Python or have dabbled a bit in programming, this tutorial will help you understand the fundamental concept of Python variables.
What Will We Learn?
In this journey of “Machine Learning for Kids” lets learn the basics of python which is the foundation of machine learning. In this tutorial, we’ll dive into what variables in Python are, how to create them, and how we can use them. We will discuss the different types of data we can store in variables and illustrate this with easy-to-understand examples.

Understanding Python Variables
In Python, a variable is created when you assign a value to it. For example, x = 5
creates a variable named x
and stores the number 5
in it. Python variables don’t require explicit declaration to reserve memory space. The declaration happens automatically when you assign a value to a variable.
You can think of variables as labels for containers that hold information or data. The data stored in a variable, known as its value, can be of various types like numbers, text (known as strings in Python), lists, and more.
Let’s illustrate this with some code:
# Creating variables
name = "John"
age = 12
fruits = ["apples", "bananas", "cherries"]
# Printing variables
print(name)
print(age)
print(fruits)
Here’s what’s happening in the code:
name = "John"
: Here, we’re creating a variable called name
and storing the string “John” in it.
age = 12
: This creates a variable called age
and stores the number 12
in it.
fruits = ["apples", "bananas", "cherries"]
: This creates a variable called fruits
and stores a list of strings in it.
print
is a function that displays the value of a variable to the console. When we print our variables, we see the values that are stored in them:
John
12
['apples', 'bananas', 'cherries']
As you can see, Python variables are flexible and allow us to store various types of data, including numbers, strings, and lists. In subsequent tutorials, we’ll explore more about different data types and how we can operate on them in Python. Happy coding!
