What difference do you make between "values" and "references" ?-)
Hint 1: in Python, all you have are objects. Yes, even strings and
numbers etc...

Hint 2 : Python has something very nice which is the interactive python
shell. This lets you try code snippets and see by yourself how it really
works :
[EMAIL PROTECTED] ~ $ python
Python 2.4.3 (#1, Sep 29 2006, 20:26:46)
[GCC 4.1.1 (Gentoo 4.1.1-r1)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> mylist = [1, "aaa"]
>>> mylist.append(42)
>>> mylist.append("lala")
>>> mylist
[1, 'aaa', 42, 'lala']
>>>
