  When Do WeUse Loops? Loops help us repeat tasks efficiently, reducing manual effort and code redundancy. Example: If it rains, take an umbrella; else, wear sunglasses.

  Python Loop StatementSyntax • 1. for - Iterate over lists, strings. • 2. while – continues to execute the block until the condition goes false.
• 10.
  While Loop • Repeatsa block of code as long as a condition is true. • Used when number of iterations is unknown. • Needs a loop control variable to change and avoid infinite loop. • Can be interrupted with break. • Example Use Cases • Taking input until a correct value is entered. • Running a game loop until the user quits. For Loop • Iterates over a sequence (e.g., list, string, range). • Used when number of iterations is known or fixed. • More readable and compact than while for definite loops. • Often used with range(), enumerate(), zip(). • Example Use Cases: • Looping through list items. • Running a loop n times.

  Break, Continue, Pass StatementUse break Exit loop prematurely continue Skip current iteration pass Placeholder – do nothing
• 12.
  Break – Immediatelyexits the current loop. Output
• 13.
  Continue - Skipsthe current iteration and goes to the next one. Output
• 14.
  Pass - Doesnothing; placeholder for future code. • Output
