python排序方法实例分析
本文实例讲述了python排序方法。分享给大家供大家参考。具体如下：
>>>defmy_key1(x): ...returnx%10 ... >>>alist=[4,5,8,1,63,8] >>>alist [4,5,8,1,63,8] >>>alist.sort()#默认升序排序 >>>alist [1,4,5,8,8,63] >>>alist.sort(reverse=True)#改为降序排序 >>>alist [63,8,8,5,4,1] >>>alist.sort(key=my_key1)#设置排序的key值 >>>alist [1,63,4,5,8,8] >>> >>>defmy_key2(x): ...returnx[1] ... >>>alist=[(5,'a'),(1,'w'),(2,'e'),(6,'f')] >>>alist.sort(key=my_key2)#根据每个元组的第二分量进行排序 >>>alist [(5,'a'),(2,'e'),(6,'f'),(1,'w')] >>>
希望本文所述对大家的Python程序设计有所帮助。
