iteration

• What is a condition controlled iteration used for?

  When the number of repetitions is unknown
• How does a condition controlled iteration terminate?

  When a condition becomes True or False
• What type of loop is used for condition controlled iteration?

  While loop
• What does the while loop check after setting tfAnswer to True?

  If tfAnswer is still False
• What is a count controlled iteration used for?

  When the number of repetitions is known
• What type of loop is used for count controlled iteration?

  For loop
• What does the range function control in count controlled loops?

  The number of iterations
• What does the range function start counting from in Python?

  0
• What does the range function do when given three parameters?

  Controls starting point and increment value
• What is printed when using range(1,10,2)?


  1, 3, 5, 7, 9
• What are the key differences between condition controlled and count controlled iterations?

  • Condition Controlled:
  • Unknown repetitions
  • Uses while loop
  • Count Controlled:
  • Known repetitions
  • Uses for loop
• What are the roles of the counter variable in condition controlled iterations?

  • Tracks the number of iterations
  • Triggers condition change when reaching a limit
  • Determines when to exit the loop
• What are the parameters of the range function in Python?

  • Start point (default is 0)
  • Stop point (exclusive)
  • Step value (default is 1)
