Why doesn't array.append print up?

Question

Consider a to be an array

print(a.append(1))

Why doesn't this print a's elements, it gives a message as None, whereas

print(a.index())

gives the desired result?

Also that's a *list*, and DON'T SHOUT. – jonrsharpe Jul 23 '19 at 13:25 — jonrsharpe, Jul 23 '19 at 13:25

Why doesn't this print a's elements

Why should it? append is meant to modify the list in-place. When you print(a.append(1)), you are appending 1 to a, and printing the result of calling append (the object returned by the append method), which is None.
