While loop

Use while loop to execute a set of statements as long as a condition is true.

n = 0
while n < 10:
  print(n)
  n += 1

In the above program, number of iterations depends on the value of n. This is an example of why while loop is considered as condition based loop.

Break

A break statement can be used to control the loop iterations. In a nutshell, break breaks the loop execution when a condition is matched.

n = 0
while n < 6:
  print(n)
  if n == 3:
    break
  n += 1

Continue

A continue statement can be used to skip an Iteration of a loop. In a nutshell, continue skips the current iteration and moves to the next iteration.

Example: Print numbers less than 10 but skip 5.

n = 0
while n < 6:
  n += 1
  if n == 5:
    continue
  print(n)
