Local Variable
Domain: Programming Fundamentals
🎯 Motivation
Variables created inside a function only exist while that function runs - they’re local.
📋 Concrete Example
def greet(): msg = 'Hi' - msg exists only inside greet(). After greet() finishes, msg is gone.
🔗 Analogy
A whiteboard in a meeting room - you write on it during the meeting, but when you leave, the next meeting erases it.
