While Loop

i = 0
while i < 5:
    print(i)
    i += 1

• break: Exit the loop.

  i = 0
  while i < 10:
      if i == 5:
          break
      print(i)
      i += 1
  

• continue: Skip the rest of the code in this iteration.

  i = 0
  while i < 10:
      i += 1
      if i % 2 == 0:
          continue
      print(i)
  

While Loop Techniques

• Combining with else: The else block after a while loop executes when the loop condition becomes false.

  i = 0
  while i < 5:
      print(i)
      i += 1
  else:
      print("Loop ended")
  

• Simulating Do-While Loop: Python doesn’t have a do-while loop, but you can simulate it.

  while True:
      print("This will execute at least once")
      if not condition:
          break
