Python List交集，並集，差集的應用

產生了兩個 List:

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

交集，並集，差集概念這裡不說，python代碼如下：

#! /usr/bin/env python# coding:utf-8listA = [1, 2, 3, 4, 5, 6]listB = [4, 5, 6, 7]# Intersectioninte = list(set(listA).intersection(set(listB)))print "Intersection:", inte# unionuni = list(set(listA).union(set(listB)))print "Union:", uni# Differencesdiff = list(set(listA).difference(set(listB)))print "Differences:", diff

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

產生了兩個List:

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

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