How do i find the largest value of an item in a nested dict in python?

killyb :

I have the following dict with a nested dict "Emotions":

I am trying to find an easy way to return the top 2 Emotion "Type" with largest 2 "Confidence" values ( in the case of this dict, it's "CONFUSED" & "ANGRY"

[
    {
        "AgeRange": {
            "High": 52,
            "Low": 36
        },
        "Emotions": [
            {
                "Confidence": 22.537073135375977,
                "Type": "ANGRY"
            },
            {
                "Confidence": 1.3983955383300781,
                "Type": "SAD"
            },
            {
                "Confidence": 1.2260702848434448,
                "Type": "DISGUSTED"
            },
            {
                "Confidence": 2.291703939437866,
                "Type": "FEAR"
            },
            {
                "Confidence": 8.114240646362305,
                "Type": "HAPPY"
            },
            {
                "Confidence": 10.546235084533691,
                "Type": "SURPRISED"
            },
            {
                "Confidence": 18.409439086914062,
                "Type": "CALM"
            },
            {
                "Confidence": 35.47684097290039,
                "Type": "CONFUSED"
            }
        ],
    }
]

i have tried things like dictmax = max(dict[Emotions][Confidence] key=dict.get) but that doesnt seem to work, and i am at a loss. I feel like there should be an easy way to retrieve just the Type, based upon the value of Confidence.

Ch3steR :

You can try this.

for d in my_list:
    out=sorted(d['Emotions'],key=lambda x:x['Confidence'],reverse=True)[:2]

[{'Confidence': 35.47684097290039, 'Type': 'CONFUSED'},
 {'Confidence': 22.537073135375977, 'Type': 'ANGRY'}]

You can use nlargest also.

from heapq import nlargest
for d in a:
    out=nlargest(2,d['Emotions'],key=lambda x:x['Confidence'])
