如何将具有相同键的字典组合在一起? [英] How can I combine dictionaries with the same keys?

问题描述

我有一个这样的词典列表:

I have a list of dictionaries like so:

dicts = [
    {'key_a': valuex1,
     'key_b': valuex2,
     'key_c': valuex3},

    {'key_a': valuey1,
     'key_b': valuey2,
     'key_c': valuey3},

    {'key_a': valuez1,
     'key_b': valuez2,
     'key_c': valuez3}
]

我想采用这些，并像这样构建一个大词典:

I would like to take these and construct a big dictionary like so:

big_dict = {
    'key_a': [valuex1, valuey1, valuez1],
    'key_b': [valuex2, valuey2, valuez2],
    'key_c': [valuex3, valuey3, valuez3]
}

我是否有任何优雅的" zip "这样的方式做这个?

Is there any elegant "zip"-like way for me to do this?

所有键总是相同的.

推荐答案

big_dict = {}
for k in dicts[0]:
    big_dict[k] = [d[k] for d in dicts]

或者，使用字典理解:

{k: [d[k] for d in dicts] for k in dicts[0]}
