Python实现的简单排列组合算法示例
本文实例讲述了Python实现的简单排列组合算法。分享给大家供大家参考，具体如下：
1.python语言简单、方便，其内部可以快速实现排列组合算法，下面做简单介绍
2.一个列表数据任意组合
主要是利用自带的库：
#_*_coding:utf-8_*_ #__author__='dragon' importitertools list1=[1,2,3,4,5] list2=[] foriinrange(1,len(list1)+1): iter=itertools.combinations(list1,i) list2.append(list(iter)) print(list2)
运行结果：
[[(1,),(2,),(3,),(4,),(5,)],[(1,2),(1,3),(1,4),(1,5),(2,3),(2,4),(2,5),(3,4),(3,5),(4,5)],[(1,2,3),(1,2,4),(1,2,5),(1,3,4),(1,3,5),(1,4,5),(2,3,4),(2,3,5),(2,4,5),(3,4,5)],[(1,2,3,4),(1,2,3,5),(1,2,4,5),(1,3,4,5),(2,3,4,5)],[(1,2,3,4,5)]]
3.排列的实现
#_*_coding:utf-8_*_ #__author__='dragon' importitertools list1=[1,2,3,4,5] list2=[] foriinrange(1,len(list1)+1): iter=itertools.permutations(list1,i) list2.append(list(iter)) print(list2)
运行结果：
[[(1,),(2,),(3,),(4,),(5,)],[(1,2),(1,3),(1,4),(1,5),(2,1),(2,3),(2,4),(2,5),(3,1),(3,2),(3,4),(3,5),(4,1),(4,2),(4,3),(4,5),(5,1),(5,2),(5,3),(5,4)],[(1,2,3),(1,2,4),(1,2,5),(1,3,2),(1,3,4),(1,3,5),(1,4,2),(1,4,3),(1,4,5),(1,5,2),(1,5,3),(1,5,4),(2,1,3),(2,1,4),(2,1,5),(2,3,1),(2,3,4),(2,3,5),(2,4,1),(2,4,3),(2,4,5),(2,5,1),(2,5,3),(2,5,4),(3,1,2),(3,1,4),(3,1,5),(3,2,1),(3,2,4),(3,2,5),(3,4,1),(3,4,2),(3,4,5),(3,5,1),(3,5,2),(3,5,4),(4,1,2),(4,1,3),(4,1,5),(4,2,1),(4,2,3),(4,2,5),(4,3,1),(4,3,2),(4,3,5),(4,5,1),(4,5,2),(4,5,3),(5,1,2),(5,1,3),(5,1,4),(5,2,1),(5,2,3),(5,2,4),(5,3,1),(5,3,2),(5,3,4),(5,4,1),(5,4,2),(5,4,3)],[(1,2,3,4),(1,2,3,5),(1,2,4,3),(1,2,4,5),(1,2,5,3),(1,2,5,4),(1,3,2,4),(1,3,2,5),(1,3,4,2),(1,3,4,5),(1,3,5,2),(1,3,5,4),(1,4,2,3),(1,4,2,5),(1,4,3,2),(1,4,3,5),(1,4,5,2),(1,4,5,3),(1,5,2,3),(1,5,2,4),(1,5,3,2),(1,5,3,4),(1,5,4,2),(1,5,4,3),(2,1,3,4),(2,1,3,5),(2,1,4,3),(2,1,4,5),(2,1,5,3),(2,1,5,4),(2,3,1,4),(2,3,1,5),(2,3,4,1),(2,3,4,5),(2,3,5,1),(2,3,5,4),(2,4,1,3),(2,4,1,5),(2,4,3,1),(2,4,3,5),(2,4,5,1),(2,4,5,3),(2,5,1,3),(2,5,1,4),(2,5,3,1),(2,5,3,4),(2,5,4,1),(2,5,4,3),(3,1,2,4),(3,1,2,5),(3,1,4,2),(3,1,4,5),(3,1,5,2),(3,1,5,4),(3,2,1,4),(3,2,1,5),(3,2,4,1),(3,2,4,5),(3,2,5,1),(3,2,5,4),(3,4,1,2),(3,4,1,5),(3,4,2,1),(3,4,2,5),(3,4,5,1),(3,4,5,2),(3,5,1,2),(3,5,1,4),(3,5,2,1),(3,5,2,4),(3,5,4,1),(3,5,4,2),(4,1,2,3),(4,1,2,5),(4,1,3,2),(4,1,3,5),(4,1,5,2),(4,1,5,3),(4,2,1,3),(4,2,1,5),(4,2,3,1),(4,2,3,5),(4,2,5,1),(4,2,5,3),(4,3,1,2),(4,3,1,5),(4,3,2,1),(4,3,2,5),(4,3,5,1),(4,3,5,2),(4,5,1,2),(4,5,1,3),(4,5,2,1),(4,5,2,3),(4,5,3,1),(4,5,3,2),(5,1,2,3),(5,1,2,4),(5,1,3,2),(5,1,3,4),(5,1,4,2),(5,1,4,3),(5,2,1,3),(5,2,1,4),(5,2,3,1),(5,2,3,4),(5,2,4,1),(5,2,4,3),(5,3,1,2),(5,3,1,4),(5,3,2,1),(5,3,2,4),(5,3,4,1),(5,3,4,2),(5,4,1,2),(5,4,1,3),(5,4,2,1),(5,4,2,3),(5,4,3,1),(5,4,3,2)],[(1,2,3,4,5),(1,2,3,5,4),(1,2,4,3,5),(1,2,4,5,3),(1,2,5,3,4),(1,2,5,4,3),(1,3,2,4,5),(1,3,2,5,4),(1,3,4,2,5),(1,3,4,5,2),(1,3,5,2,4),(1,3,5,4,2),(1,4,2,3,5),(1,4,2,5,3),(1,4,3,2,5),(1,4,3,5,2),(1,4,5,2,3),(1,4,5,3,2),(1,5,2,3,4),(1,5,2,4,3),(1,5,3,2,4),(1,5,3,4,2),(1,5,4,2,3),(1,5,4,3,2),(2,1,3,4,5),(2,1,3,5,4),(2,1,4,3,5),(2,1,4,5,3),(2,1,5,3,4),(2,1,5,4,3),(2,3,1,4,5),(2,3,1,5,4),(2,3,4,1,5),(2,3,4,5,1),(2,3,5,1,4),(2,3,5,4,1),(2,4,1,3,5),(2,4,1,5,3),(2,4,3,1,5),(2,4,3,5,1),(2,4,5,1,3),(2,4,5,3,1),(2,5,1,3,4),(2,5,1,4,3),(2,5,3,1,4),(2,5,3,4,1),(2,5,4,1,3),(2,5,4,3,1),(3,1,2,4,5),(3,1,2,5,4),(3,1,4,2,5),(3,1,4,5,2),(3,1,5,2,4),(3,1,5,4,2),(3,2,1,4,5),(3,2,1,5,4),(3,2,4,1,5),(3,2,4,5,1),(3,2,5,1,4),(3,2,5,4,1),(3,4,1,2,5),(3,4,1,5,2),(3,4,2,1,5),(3,4,2,5,1),(3,4,5,1,2),(3,4,5,2,1),(3,5,1,2,4),(3,5,1,4,2),(3,5,2,1,4),(3,5,2,4,1),(3,5,4,1,2),(3,5,4,2,1),(4,1,2,3,5),(4,1,2,5,3),(4,1,3,2,5),(4,1,3,5,2),(4,1,5,2,3),(4,1,5,3,2),(4,2,1,3,5),(4,2,1,5,3),(4,2,3,1,5),(4,2,3,5,1),(4,2,5,1,3),(4,2,5,3,1),(4,3,1,2,5),(4,3,1,5,2),(4,3,2,1,5),(4,3,2,5,1),(4,3,5,1,2),(4,3,5,2,1),(4,5,1,2,3),(4,5,1,3,2),(4,5,2,1,3),(4,5,2,3,1),(4,5,3,1,2),(4,5,3,2,1),(5,1,2,3,4),(5,1,2,4,3),(5,1,3,2,4),(5,1,3,4,2),(5,1,4,2,3),(5,1,4,3,2),(5,2,1,3,4),(5,2,1,4,3),(5,2,3,1,4),(5,2,3,4,1),(5,2,4,1,3),(5,2,4,3,1),(5,3,1,2,4),(5,3,1,4,2),(5,3,2,1,4),(5,3,2,4,1),(5,3,4,1,2),(5,3,4,2,1),(5,4,1,2,3),(5,4,1,3,2),(5,4,2,1,3),(5,4,2,3,1),(5,4,3,1,2),(5,4,3,2,1)]]
