Application of Python List intersection, union, and difference set

Generated two List:

A = ['apple','apple','banana']
B = ['banana','apple','banana']

The concepts of intersection, union, and difference set are not discussed here. The python code is as follows:

#! /usr/bin/env python
# coding:utf-8

listA = [1, 2, 3, 4, 5, 6]
listB = [4, 5, 6, 7]

# Intersection
inte = list(set(listA).intersection(set(listB)))
print "Intersection:", inte

# union
uni = list(set(listA).union(set(listB)))
print "Union:", uni

# Differences
diff = list(set(listA).difference(set(listB)))
print "Differences:", diff

if diff:
    print "wrong"
else:
    print "matched"
