How to get value from nested data

Question

I want maximum scorer from this complicated data, but it shows error, maybe I am doing something wrong here.

students = {
    'harshit':{'score':90, 'age':22},
    'Mohit':{'score':79, 'age':20},
    'Rohit':{'score':99, 'age':29}
}

print((max(students , key= lambda item: item.get('score'))))

I expected the output : Rohit
but here I got an error cox they're saying item is a string but for my case it is also a key

@TheGamer007 I don't think it's dup as OP wants to find max within nested dict. — Sociopath, Feb 04 '19 at 05:23
Yeah but i have more complicated dictionary but wait now i'm trying ,,,, maybe i'll get my solution now because i'm operating my 'item' but they are accessing direct their root dictionary so wait i'm trying sir — Ankit Singh, Feb 04 '19 at 05:24

you probably want this -

students = {
    'harshit':{'score':90, 'age':22},
    'Mohit':{'score':79, 'age':20},
    'Rohit':{'score':99, 'age':29}
}

print((max(students , key= lambda item: students[item].get('score'))))

By lambda you are specifying the key. So students[item] to iterate over the students and then get('score') to get score for a particular entry.

Ohh I Got it!! Now i'm accessing my key from main dictionary then inside elements

students = {
    'harshit':{'score':9, 'age':22},
    'Mohit':{'score':9, 'age':20},
    'Rohit':{'score':9, 'age':29}
}
print((max(students , key= lambda item: students[item]['score'])))
