In the continue Loop - i = 0 while True: i = i +1 if i == 2: print("Skipping 2") continue if i == 5: print("Breaking") break print(i) print("Finished") It shows the output being "1 Skipping 2 3 4 Breaking Finished" Why are the last three lines not "Breaking 5 Finished" Where it shows print(i) after break?
