With sets you can do union, intersection, ect. Or:
>>> l1 = [1, 2, 3, 4]
>>> l2 = [2, 3]
>>> list(set(l1) - set(l2))
[1, 4]
>>>

you should be able to understand how to use sets by now, since barton has showed you how here

If you do not want to use sets, you could do this:

>>> lst1 = [1,2,3,4,5,6,7,8,9,0,11,12,13]
>>> lst2 = [5,6,7,12,45,67,89,99]
>>> [i for i in lst1+lst2 if i not in lst1 or i not in lst2]
[1, 2, 3, 4, 8, 9, 0, 11, 13, 45, 67, 89, 99]
