While Loop

While loop is another type of loops. It performs the same, but the construction of the loop differs.


              12345678910
            
# Summing all prices
prices = [3, 5, 6, 2, 7, 8]
i = 0
counter = 0

while i < len(prices):
  counter += prices[i]
  i += 1

print(counter)

When we want to stop our loop immediately, we need to use break.


              123456789
            
prices = [1, 2, 3, 4, 5, 6]
i = 0

while i < len(prices):
  if prices[i] == 4:
    break
  else:
    print(prices[i])
  i += 1

We use a special variable (counter in our case) to collect elements of the price list (in our case). If you want to count the sum of the numbers from 1 to 10, you also have to create a variable that collects the sum after each iteration.

Tarea

Let's count all money from the list until the sum equals the 100!

Set the while loop to work with the money list.
Set the condition if the counter equals 100.
Finish the program if the counter equals 100.
Add the money iterator to the counter.
Increase the i by 1.
Print the counter.
