Day 5 - Python Quiz (Nested Loops & Patterns)

What is a Nested Loop?
A nested loop is a loop inside another loop.

Why Nested Loops?

• Used when one repetition depends on another
• Mainly used for pattern printing
• Used in matrices, tables, grids, games

Structure of Nested Loop

for i in range(...):
    for j in range(...):
        statements

How Nested Loop Works

• Outer loop runs first
• Inner loop runs fully for each outer loop iteration

Pattern Printing Concept

• Outer loop → number of rows
• Inner loop → number of columns
• print("*", end=" ") prints in same line
• print() moves to next line

Example: Simple Star Pattern

for i in range(3):
    for j in range(3):
        print("*", end=" ")
    print()

Important Points

• Indentation is very important
• Understand loop flow before memorizing
• Patterns help improve logic
