If you can post an example where you show us the actual content of the two
list you are comparing, it will be much easier to help you find what might
be wrong.
Something like:
a = {1, 2, 3}
b = {2, 3, 4}print a - b # Remove items from a that exist in b#
1print b - a # Remove items in b that exists in a# 4print a ^ b #
Symmetrical difference between a and b# [1, 4]
All the operations can be found here:
