Python discord bot command with json database - json

Question

So I'm making a command that is !command
When you type that in a chat it will update the member(s) score in the database.
The database will look something like this
{
"person": "epikUbuntu"
"score": "22"
}
How would I go on doing that?
edit:
If I wasn't clear I meant ho would I go on doing the python part of it?

JSON objects in python work like dictionaries.
You can write a new dictionary and save it:
data = {"foo": "bar"}
with open("file.json", "w+") as fp:
json.dump(data, fp, sort_keys=True, indent=4) # kwargs for beautification
And you can load data from a file (this will be for updating the file):
with open("file.json", "r") as fp:
data = json.load(fp) # loading json contents into data variable - this will be a dict
data["foo"] = "baz" # updating values
data["bar"] = "foo" # writing new values
with open("file.json", "w+") as fp:
json.dump(data, fp, sort_keys=True, indent=4)
Discord.py example:
import os # for checking the file exists
def add_score(member: discord.Member, amount: int):
if os.path.isfile("file.json"):
with open("file.json", "r") as fp:
data = json.load(fp)
try:
data[f"{member.id}"]["score"] += amount
except KeyError: # if the user isn't in the file, do the following
data[f"{member.id}"] = {"score": amount} # add other things you want to store
else:
data = {f"{member.id}": {"score": amount}}
# saving the file outside of the if statements saves us having to write it twice
with open("file.json", "w+") as fp:
json.dump(data, fp, sort_keys=True, indent=4) # kwargs for beautification
# you can also return the new/updated score here if you want
def get_score(member: discord.Member):
with open("file.json", "r") as fp:
data = json.load(fp)
return data[f"{member.id}"]["score"]
#bot.command()
async def cmd(ctx):
# some code here
add_score(ctx.author, 10)
# 10 is just an example
# you can use the random module if you want - random.randint(x, y)
await ctx.send(f"You now have {get_score(ctx.author)} score!")
