bookWhile Loop

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

We use a special variable, i.e. counter, to collect elements of the list. If you want to count the sum of the numbers from 1 to 10 using the while loop, you also have to create a variable that collects and updates the sum after each iteration.

We use len() when creating a while loop function to create a suitable iterable.

123456789
prices = [100, 458, 231, 378] i = 0 counter = 0 while i < len(prices): counter += prices[i] i += 1 print(counter)
copy
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)
copy

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
copy

War alles klar?
