# append method

I was going through the tutorial, working with lists and the fib function,
when I found a curious thing. Here's the transcript:

>>> def fib(n):
... result = []
... a, b = 0, 1
... while b<=n:
... result.append(b)
... a, b = b, a+b
... return result

>>> list=[100,fib(100),200,fib(200)]
>>> list
[100, [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89], 200, [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144]]
>>> list.append(300,fib(300))
>>> list
[100, [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89], 200, [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144], (300, [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233])]

Why are there parenthesis around the appended element?
