Dumb down your problem to something simpler.

saving 2 lists of 2 numbers.

1/ for saving/loading the list, use pickle if *you* will do the saving 
*and* the loading (don't load from an untrusted file)

2/ To compare 2 lists, simply use the == operator

In [4]: [[1,2], [1,2]] == [[1,2], [1,3]]
Out[4]: False

In [5]: [[1,2], [1,2]] == [[1,2], [1,2]]
Out[5]: True
