Get difference between two lists

Question

I have two lists in Python, like these:

temp1 = ['One', 'Two', 'Three', 'Four']
temp2 = ['One', 'Two']

I need to create a third list with items from the first list which aren't present in the second one. From the example I have to get:

temp3 = ['Three', 'Four']

Are there any fast ways without cycles and checking?

def diff(listA, listB):
    return set(listA) - set(listB) | set(listA) -set(listB)
