Variables
Learn how to store data in variables. Variables are like labeled boxes where you can put information.
Theory
A variable is a name that refers to a value stored in computer memory.
To create a variable, use the = sign:
name = "Alice"
age = 25
The variable name is on the left, and the value is on the right.
You can then use variables in print():
print(name) # Will display: Alice
print(age) # Will display: 25
