Loop Examples for 6th Grade: Coding Repetitive Tasks

📚 Quick Study Guide

• 🔁 What is a Loop? A loop is a programming tool that repeats a set of instructions multiple times.
• 🔢 Why Use Loops? Loops save time and effort by automating repetitive tasks. Imagine drawing 100 circles without a loop – yikes!
• ✨ Types of Loops: The most common types are 'for' loops and 'while' loops.
• 'For' loops repeat a specific number of times.
• 'While' loops repeat as long as a condition is true.
• ✏️ 'For' Loop Example: In Python: `for i in range(5): print("Hello")` (This prints "Hello" 5 times).
• ✅ 'While' Loop Example: In Python: `count = 0; while count < 3: print(count); count = count + 1` (This prints 0, 1, and 2).
