合并具有相同键和不同值的两个字典 [英] Consolidating two dictionaries with the same keys and different values

问题描述

我有两个 collection.Counter()s，它们都是相同的键，所以它们看起来像这样:

I have two collection.Counter()s, both of which of the same keys, so they look something like this:

01: 3
02: 2
03: 4

01: 8
02: 10
03: 13

我希望最终结果看起来更像这样:

I want the final result to look a bit more like this:

01: [3, 8]
02: [2, 10]
03:  [4, 13]

我将如何合并它们?

推荐答案

您可以使用 字典理解:

dict1 = {1: 3, 2:  2, 3:  4 }
dict2 = {1: 8, 2: 10, 3: 13 }
dict3 = { k: [ dict1[k], dict2[k] ] for k in dict1 }
# Result:
# dict3 = {1: [3, 8], 2: [2, 10], 3: [4, 13]}
