Iteration and the While Loop

When you don't know how many times to repeat something, how does a `while` loop keep running until its condition finally turns false?

Exercise 1 of 5

Mentally execute this loop and predict the final value of total after it finishes:

n = 3
total = 0
while n > 0:
    total = total + n
    n = n - 1

Assign that final value to final_total.

# Predict the value total holds once the loop in the prompt finishes.
final_total = ...  # your code here

# Predict the value total holds once the loop in the prompt finishes.
final_total = ...  # your code here
