Comparing lists ...

[Loic]

I would like to know if it is possible, and how to do this with Python:

I want to design a function to compare lists and return True only if 
both lists are equal considering memory location of the list.
I suppose it would be the equivalent of comparing 2 pointers in c++

lets call this function check(a, b)
and define a few lists:

 >>> l0 = [1, 2, 3, 4]
 >>> l1 = [1, 2, 3, 4]
 >>> l2 = l0

I want it to have the following behaviour:

 >>> check(l1, l0)
False

 >>> check(l2, l0)
True

 >>> check(l1, l2)
False


Any idea how to do this with Python?
