How to find a value of a key in a nested dictionary with lists?-CodePudding

There's some very strange json payloads that I need to parse and I'm complete stuck..

Say I have a nested dictionary with lists that looks like this:

test_dict1 = {
    "blah":"blah", 
    "alerts": [{"test1":"1", "test":"2"}], 
    "foo": {
        "foo":"bar", 
        "foo1": [{"test3":"3"}]
        }}

Is there a function that would be able to give me the value of the key test3? Or rather the first value for the first occurrence of the key test3

CodePudding user response：

Just access it like you would any other nested structure:

test_dict1["foo"]["foo1"][0]["test3"]

Also, what do you mean by the first occurrence? Dictionaries don't have a specific order, so that won't really do much for you.

CodePudding user response：

If you only want the value of test3 then this is how you can get it,

test_dict1["foo"]["foo1"][0]["test3"]

But if you want value dynamically then it will be done with a different approch. See, you can use a key name when you are working with dictionaries and indexing when it comes to the list.
