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: >>> def my_key1(x): ... return x ... >>> 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) #
