Our expert team is currently recording the visual guide for Variables.
The Core Concept
Variables are just names that point to values stored in your computer's memory. Think of a variable as a labeled container or a sticky note. You write a label, assign it a value using the equals sign (=), and Python stores it. Later, you can just use that label instead of typing the value again.
Python is smart enough to figure out what kind of data you're storing. You don't need to declare if it's text or a number beforehand. You can also reassign a variable to a different value at any time.

Code & Implementation
# Assigning values to variables
username = "Alex_Dev"
login_attempts = 3
is_active = True
# Printing variables
print("User name is:", username)
print("Attempts remaining:", login_attempts)
# Modifying a variable value
login_attempts = login_attempts - 1
print("Updated attempts:", login_attempts)Expected Output
User name is: Alex_Dev Attempts remaining: 3 Updated attempts: 2

Hands-on practice task
The Challenge
Create a script that stores a team's name and their score. Start the score at 0, simulate scoring a goal (add 1 point), and print the updated board.
Helpful Hints
- •Set team_name = "Warriors" and score = 0.
- •Update the score with score = score + 1.
- •Print both variables together.
