Updating JSON when there is multiple objects named the same - Python

Question

I am new to the JSON python lib.

I have this JSON file:

   {
        "usrdata": [
            {
                "user": "---/ LandiPlayz \\---#****",
                "money": 10
            },
            {
                "user": "Snubz#****",
                "money": 10
            }
        ]
    }

and I need to modify the "money" field of one of the users. There will be more added users, so I need to find which one it is by finding the users name. Is that possible, or should I do format the file differently.

Thanks in advance

You can, you just need to know the user value. No matter how the JSON values are , if the you have the info to reach the value, you'll be good — azro, May 28 '20 at 19:17
You don't really edit the file; you decode it, modify the resulting in-memory data structure, and write out a new file. — chepner, May 28 '20 at 19:20

You have to iterate over the user_infos, and when getting the good one, update the money

json_value =    {
        "usrdata": [
            {"user": "---/ LandiPlayz \\---#****","money": 10},
            {"user": "Snubz#****","money": 10}
        ]
    }
username = "Snubz#****"
new_money = 50

for user_info in json_value["usrdata"]:
    if user_info['user'] == username:
        user_info['money'] = new_money
