Get second largest number from json object in python-CodePudding

I am trying to get the second largest value from a json file. I have managed to get the largest value but not the second value, how would I do this?

this is what I have so far:

    with open('leaderBoard.json') as f:
        events = json.load(f)
        event = max(events['names'], key=lambda ev: ev['points'])
        print(event)

output:

{'PrevStreak': False, 'Streak': 0, 'name': 'kk#7565', 'points': 2000}

and this is my json file:

{
    "names": [

        {
            "PrevStreak": false,
            "Streak": 0,
            "name": "kk#7565",
            "points": 2000
        },

        {
            "PrevStreak": false,
            "Streak": 0,
            "name": "ff#7565",
            "points": 100
        }
    ]
}

any help is great, Thanks

You could first sort json and then get the value:

with open('leaderBoard.json') as f:
        events = json.load(f)
        events = sorted(events["names"], key=lambda ev: ev["points"])
        event = events[-2]
        print(event)

Assuming 0 is the minimal number of points,

with open('leaderBoard.json') as f:
    events = json.load(f)
    max_points = max(events['names'], key=lambda ev: ev['points'])
    2nd_points = max(events['names'], key=lambda ev: ev['points'] if ev['points'] < max_points else 0)
    print(2nd_points)
