while loop in python programming

  • A Python ‘while loop’ repeatedly carries out a target statement while the condition is true.
  • The loop iterates as long as the defined condition is true. When it ceases to be true and becomes false, control passes to the first line after the loop.
  • Python while statement is the most general iteration construct in the language.
  • Its called a loop because control keeps looping back to the start of the statement until the test becomes false.
