从python字典获取最高键 [英] Getting the highest key from python dictionary

问题描述

我有一个带值的python字典，我需要搜索最大键.

I have a python dictionary with values and I need to search the maximum key.

data={'A': 1,'C': 3, 'H': 1,'I': 1, 'B': 1,'J': 2,'S': 1, 'D': 3, 'N': 2}

我尝试max(data, key=data.get).这给出了C的答案.但是我想获得C& D作为答案，因为C和D都是最高的数字.

I try max(data, key=data.get).This gives the C as an answer.But I'd like to get C & D as an answer,since both C and D are the highest number.

如何在Python中完成此操作?

推荐答案

单独使用max不能完成此操作，因为max仅返回单个元素.相反，首先从data获取max值，然后过滤具有相同值的那些键.

You can not do this with max alone, as max will only return a single element. Instead, first, get the maxvalue from data, then filter those keys that have the same value.

>>> data={'A': 1, 'T': 1, 'C': 3, 'H': 1, 'I': 1, 'B': 1, 'O': 1,'J': 2, 'Q': 1, 'S': 1, 'D': 3, 'N': 2}
>>> max_val = max(data.values())
>>> [key for key, val in data.items() if val == max_val]
['C', 'D']
