I'm wondering if there's a simple function that will return the difference between two lists OR dictionary items. For example, say i've got the following: A: [a, b, c, d, e, f, g, h, i] B: [a, b, d, c, e, g, f, i, h] I would like to know if there's a comparison function that will tell me there are 6 differences between lists A,B Thanks, M
