  Adele - "Rolling in the Deep"
  There's a fire starting in my heart Reaching a fever pitch and it's bringing me out the dark Finally, I can see you crystal clear Go ahead and sell me out and I'll lay your ship bare See how I'll leave with every piece of you Don't underestimate the things that I will do There's a fire starting in my heart Reaching a fever pitch and it's bring me out the dark The scars of your love remind me of us They keep me thinking that we almost had it all The scars of your love, they leave me breathless I can't help feeling We could have had it all (You're gonna wish you never had met me) Rolling in the deep (Tears are gonna fall, rolling in the deep) You had my heart inside of your hands (You're gonna wish you never had met me) And you played it to the beat (Tears are gonna fall, rolling in the deep)

Oto przykład wykorzystania pętli while w Pythonie:

w = 0 while w == 0: w = int(input("Podaj liczbę większą od zera: ")) if w <= 0: print("Hej! Miała być większa od zera!") else: print("Twój szczęśliwy numerek to {number}.\n\nKoniec programu!".format(number = w))

Użycie słowa kluczowego else jest tutaj opcjonalne.
