I must point out though that although they contain
the same elements/data, they are not the same
object/instance.

{{{
#!python
>>> x = [1, 2, 3]
>>> y = [1, 2, 3]
>>> id(x)
3083095148L
>>> id(y)
3082953324L
>>> x == y
True
}}}

If you view the documentation for a list:
{{{
#!sh
$ pydoc list
}}}

list's have an __eq__ that is used to compare the
equality of 2 lists.
