Why is the interpreter is returning a 'reference'?


>>> k = ['hi','boss']
>>>
>>> k
['hi', 'boss']
>>> k= [s.upper for s in k]
>>> k
[<built-in method upper of str object at 0x00000000021B2AF8>, <built-in method upper of str object at 0x0000000002283F58>]

Why doesn't the python interpreter just return
['HI, 'BOSS'] ?

This isn't a big deal, but I am just curious as to why it does this.
