August 31, 2021 - The while loop, on the other hand, doesn't run at least once and may in fact never run. It runs when and only when the condition is met. So, let's say we have an example where we want a line of code to run at least once. secret_word = "python" counter = 0 while True: word = input("Enter the secret word: ").lower() counter = counter + 1 if word == secret_word: break if word != secret_word and counter > 7: break

Here is a while loop to print the numbers 0, 1, 2, ... 9 (there are easier ways to do this, but here we're just trying to show the parts of the loop). i = 0 while i < 10: print(i) i = i + 1 print('All done') 0 1 2 3 4 5 6 7 8 9 All done · Very often the last line of the while body has an "increment" role, such as the i = i + 1 line above.
