How to change a value in json file within a loop?

Question

I'm using a JSON file to store the number of warnings a user has. When a user is warned, I want to increase the number of warnings.

This is the JSON sample I use :

{
"users": {
    "976797937789198397" : "1",
    "270904126974590976" : "2",
    "871490226692976791" : "1"

}  }

This is the code I use to fetch the number of warnings a user has, and this works without any errors. I just need a way to find out how to add +1 to a user every time they are warned.

@commands.command()
async def getWarns(self, ctx : commands.Context, member : discord.Member):
    with open('warns.json') as f:
        data = json.load(f)
        await ctx.send(data["users"][f"{member.id}"])

You just retrieve a value of the outer dictionary which is also a dictionary. Then you get, modify and set a value of the inner dictionary. What is the problem? — Michael Butscher

You can use int() to convert the value of the specific ID to int, then increase it by 1. Something like:

f = {
"users": {
    "976797937789198397" : "1",
    "270904126974590976" : "2",
    "871490226692976791" : "1"

}  }

warn_int = int(f['users']['976797937789198397'])

if userIsWarned:
    warn_int = warn_int +1
    f['users']['976797937789198397'] = str(warn_int)
