why it prints None?

lista = [1,2,3,4,5,6] print(lista.extend([7,8]))

print() is supposed to display the return value of the lista.extend() method. But there's nothing to return really, it just extends lista by the list [7, 8]. So the default return value, None, is printed. If you want to see how lista looks now, just print it after extending: lista.extend([7,8]) print(lista) Hope that helps 😊
