从python中的嵌套字典中获取所有值 [英] Get all values from nested dictionaries in python

问题描述

我有一些字典的字典，像这样:

I have some dictionaries of dictionaries, like this:

a['b']['c']['d']['answer'] = answer1
a['b']['c']['e']['answer'] = answer2
a['b']['c']['f']['answer'] = answer3
....
a['b']['c']['d']['conf'] = conf1
a['b']['c']['e']['conf'] = conf2
a['b']['c']['f']['conf'] = conf3

是否有一种快速的方法可以获取第三级 (d,e,f) 上所有元素的所有答案的值列表?

Is there a fast way to get a list of values of all answers for all elements at the third level (d,e,f)?

特别是我想知道是否有任何实现通配符的机制(例如，a['b']['c']['*']['answer'].values()

Specifically I'd like to know if there's any mechanism implementing a wildcard (e.g., a['b']['c']['*']['answer'].values()

更新到目前为止，我发现的最快方法是:

update The fastest way I've found till now is:

[x['answer'] for x in a['b']['c'].values()]
