Adding values in a json file

I'm trying to add previously added integers in the json file. for discord.py

@client.command()
async def mine(ctx):
await open_account(ctx.author)

users = await get_wallet_data()

user = ctx.author


earnings = int(random.randrange(11))

em = discord.Embed(title = 'Mined NeoCoins')
em.add_field(name = 'Earnings:', value = earnings)
await ctx.send(embed = em)


wallet_amt = users[str(user.id)]['Wallet']
print(wallet_amt)
nw = wallet_amt =+ earnings
nw = users[str(user.id)]['Wallet']
print(nw)


with open('wallet.json','w') as f:
    users =  json.dump(users,f)

But I'm getting that same value. Not the added value

To change the values of .json files, you have to load the file first, make the edits, and then replace the file with the changed version.

Load file:

with open("filename.json", "w+") as fp:
    d = json.load(fp) #load the file as an object

Make edits:

    ... #change the values in d

Replace file with changed version:

    fp.truncate(0) #empty the file
    json.dump(d, fp) #dump changed version into file
