Before anything else: what is Python? Well, it’s not a snake (sorry if that disappoints anyone), but rather a programming language that can do all sorts of cool stuff like automating tasks and making your life easier. And the best part? It’s super easy to learn!

Now, some basic concepts you need to know before diving into Python: variables, data types, operators, and control structures (don’t worry if those terms sound foreign we’ll explain them all in a sec).

Variables are like little boxes that hold information. You can give each box a name (like “my_name” or “age”) and then put something inside it (like your actual name or age). To create a variable, simply assign a value to it using the equals sign:

# Example 1
# Creating a variable called 'x' and assigning it a value of 5
x = 5
# Printing out the value stored in 'x' (which is currently 5)
print(x)

# Example 2
# Creating a variable called 'my_name' and assigning it a string value
my_name = "John Doe"
# Printing out the value stored in 'my_name' (which is currently "John Doe")
print(my_name)

Data types are like categories for variables. There are four main data types in Python: integers, floats, strings, and booleans. Integers are whole numbers (like 5 or -10), while floats have decimal points (like 3.14). Strings are sequences of characters (like “hello” or “Python is awesome”), and booleans can only be either True or False.

Operators are like tools that help you manipulate data. There are all sorts of operators in Python, but we’ll focus on the basic ones for now: addition (+), subtraction (-), multiplication (*), division (/), modulus (%), and exponentiation (**) .

Control structures allow you to control the flow of your code based on certain conditions. There are three main types of control structures in Python: if statements, loops, and functions. If statements let you check for specific conditions and execute a block of code only if that condition is true. Loops let you repeat a set of instructions multiple times (like printing out the numbers 1-10), while functions allow you to group together related tasks and reuse them whenever needed.

Now, let’s put all these concepts into action with some fun examples! Here’s how you can use Python to calculate your age based on your birth year:

# Example 3
# This script calculates the age of a person based on their birth year and the current year.

# Prompt the user to enter the current year and store it in the variable 'year'
year = int(input("Enter the current year: "))

# Prompt the user to enter their birth year and store it in the variable 'birth_year'
birth_year = int(input("Enter your birth year: "))

# Calculate the age by subtracting the birth year from the current year and store it in the variable 'age'
age = year - birth_year

# Print a message that includes the calculated age
print("You are", age, "years old!")

With just a few lines of code, we’ve created a program that can calculate your age based on your birth year. Pretty cool, huh?

Of course, this is just scratching the surface Python has so much more to offer (like lists, dictionaries, and functions) but for now, let’s focus on mastering these basic concepts.
