Python list降序排序

test = [6,1,2,3,4,5]
a =  sorted(test,reverse=True)
print a
結果如下：
[6, 5, 4, 3, 2, 1]
你可以參考下sorted,里面是可以接收reverse參數的
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
