Python While Loops

Python While Loops

Python has two primitive loop commands:

• while loops
• for loops

With the while loop we can execute a set of statements as long as a condition is true.

i = 1
while i < 6:
  print(i)
  i += 1

Note: Remember to increment i, or else the loop will continue forever (an infinite loop).

The break Statement

With the break statement we can stop the loop even if the while condition is true.

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

The continue Statement

With the continue statement we can stop the current iteration, and continue with the next.

i = 0
while i < 6:
  i += 1
  if i == 3:
    continue
  print(i)
