Document Summary

Executes instructions repeatedly until goal is reached. Flow of execution loops again to the point where condition is tested. Keeps getting tested until goal is reached. While balance < target: while statement. Interest =balance * rate / 100 body of while statement. Aka while means as long as condition is true. Infinite loop if condition never becomes false: kill a hanging system by ctrl + c, don"t forget to update variable in the while statement. Update variable inside loop: something inside the loop should change one of the variables used in the test. Count controlled bc controlled by counter: counter = 1, while counter <= 10 , print(counter, counter = counter + 1. Event-controlled bc executes until an event occurs: while balance < target , year = year + 1, balance = balance + interest interest = balance * rate / 100. Definite if you know how many iterations it takes to reach goal.
