Day 4 Python Quiz - Loops

What is a Loop?
A loop is used to repeat the same block of code multiple times without writing it again and again.

Why Loops?

  • To reduce repeated code
  • To perform tasks multiple times easily
  • To save time and effort

Types of Loops in Python

  • while loop – condition based loop
  • for loop – sequence based loop

while Loop

  • Runs while a condition is True
  • Condition is checked before every iteration
  • Loop variable must be updated

for Loop

  • Used when number of repetitions is known
  • Mostly used with range()

range() Function

  • range(5) → generates 0 to 4
  • range(1, 6) → generates 1 to 5
  • range(2, 11, 2) → generates even numbers
  • Stop value is always excluded

break Statement
Used to stop the loop completely.

continue Statement
Used to skip the current iteration.

pass Statement
Used as a placeholder. It does nothing.

Infinite Loop
Happens when loop condition never becomes False.

Key Points

  • Use for loop when count is known
  • Use while loop when condition is unknown
  • Indentation is very important in loops
