I am 14 and I finally understood why this prints None in Python

I used to be confused about why this prints None:

numbers = [1, 2, 3]
print(numbers.append(4))

At first I thought append() would return the updated list.

But append() actually modifies the list in place and returns None.

So Python is effectively doing this:

print(None)

The correct way is:

numbers.append(4)
print(numbers)

Just sharing in case other beginners were confused like I was.

Is there another way you like to explain this concept to beginners?
