test = [6,1,2,3,4,5] a = sorted(test,reverse=True) print a 结果如下: [6, 5, 4, 3, 2, 1] 你可以参考下sorted,里面是可以接收reverse参数的 def sorted(iterable, cmp=None, key=None, reverse=False): # real signature unknown; restored from __doc__ """ sorted(iterable, cmp=None, key=None, reverse=False) --> new sorted list """ pass
