Python-查找字典中最长(最多单词)的键 [英] Python - Find longest (most words) key in dictionary

问题描述

有没有一种方法可以快速查询字典对象，以便找到词最多的键(所有键都是字符串类型)?

Is there a way to quickly query a dictionary object in order to find the key (all keys are of string type) with the most words?

也就是说，如果键最大的项有五个词{'this is the first key':3}，我该如何快速查询字典并返回整数'5'?

I.e., if the item with the largest key had five words {'this is the largest key': 3}, how could I quickly query the dict and have the int '5' returned?
