I have sort of a similar question as Find matching keys in dictionaries & replace keys with values

However my situation looks like this.

d1 = {"1": "DNS Compromise", "2": "DNS Poisoning", "3": "Fraud Orders"}
d2 = {... ,"categories": [1, 2], ...}

I would like to have the following output:

d2 = {..., "categories": [DNS Compromise, DNS Poisoning], ...}

Is there a way to construct a for loop or use comprehension? I am sort of new to this.

CodePudding user response：

With dictionary you can easily get a list of the values with the method values().

d2 = {"categories": d1.values()}

This is the solution you are searching for : d3 = {k:[ d1[str(v_i)] for v_i in v] for k,v in d2.items() }
