Python | 实现字典倒序输出
作者:互联网
Python 字典 将字典进行倒序翻转
>>> dic = {"a":1,"c":2,"b":3}
>>> dic
{'a': 1, 'c': 2, 'b': 3}
>>> keys = list(dic.keys())
>>> values = list(dic.values())
>>> keys.reverse()
>>> values.reverse()
>>> dict(zip(keys,values))
{'b': 3, 'c': 2, 'a': 1}
暂时想到这个方法,有点繁琐,后面有想到更优的方法再来优化。
如果你想到了,欢迎评论告诉我喔!
Python 字典 按key值大小 将字典进行从大到小排序
>>> new_dic = {}
>>> dic = {"a":1,"c":2,"b":3}
>>> for key in sorted(dic.keys(),reverse=True):
new_dic[key]=dic.get(key)
>>> new_dic
{'c': 2, 'b': 3, 'a': 1}
>>>
