Question

我想以管理员身份为特定会员的余额添加积分了解如何使用某人的所有“要点”创建JSON文件。

import discord
from discord.ext import commands
import random
import os
import json


# this line of code gives the bot a comand prefix
bot = commands.Bot(command_prefix="/")

# This line of code tells the bot to start up
@bot.event
async def on_ready():
  print("The bot is now online!")

@bot.command(pass_context=True)
async def leaderboard(ctx):
  await ctx.send("This is a work in progress, this will dieplay the leaderboard")
amounts = {}

@bot.command(pass_context=True)
async def balance(ctx):
    id = str(ctx.message.author.id)
    if id in amounts:
        await ctx.send("You have {} ben points".format(amounts[id]))
    else:
        await ctx.send("You do not have an account")

@bot.command(pass_context=True)
async def register(ctx):
    id = str(ctx.message.author.id)
    if id not in amounts.keys:
        amounts[id] = 100
        await ctx.send("You are now registered")
        _save()
    else:
        await ctx.send("You already have an account")

@bot.command(pass_context=True)
async def transfer(ctx, amount: int, other: discord.Member):
    primary_id = str(ctx.message.author.id)
    other_id = str(other.id)
    if primary_id not in amounts:
        await ctx.send("You do not have an account")
    elif other_id not in amounts:
        await ctx.send("The other party does not have an account")
    elif amounts[primary_id] < amount:
        await ctx.send("You cannot afford this transaction")
    else:
        amounts[primary_id] -= amount
        amounts[other_id] += amount
        await ctx.send("Transaction complete")
    _save()

def _save():
    with open('amounts.json', 'w+') as f:
        json.dump(amounts, f)

@bot.command()
async def save():
    _save()

#This line of code tells the bot to run
bot.run("Token")

我不确定从这里开始我打算做什么。

如果有人可以提高代码效率，我可能会过于复杂，我将非常感激。

这是基本用法，以及您需要了解JSON基础知识的所有内容：

# Creating a dictionary with some values
>>> data = {"foo": "bar", "key": "value"}

# Opening a file and writing to it
>>> with open("db.json", "w+") as fp:
...     json.dump(data, fp, sort_keys=True, indent=4) # Kwargs for beautification

# Loading in data from a file
>>> with open("db.json", "r") as fp:
...     data = json.load(fp)

# Accessing the values
>>> data["foo"]
'bar'
>>> data["key"]
'value'

这可以适合您的需求，例如：

# Let's say the JSON has the following structure:
# {"users": {112233445566778899: {"points": 0}, 224466881133557799: {"points": 0}}}
# The "users" key is a bit redundant if you're only gonna store users in the file.
# It's down to what you'll be storing in the file and readability etc.
import json
import random
import typing

def add_points(member_id: str, amount: int):
    # Open the file first as to load in all the users' data
    # Making a new dict would just overwrite the current file's contents
    with open("file.json", "r") as fp:
        data = json.load(fp)
    data["users"][member_id]["points"] += amount
    # Write the updated data to the file
    with open("file.json", "w+") as fp:
        json.dump(data, fp, sort_keys=True, indent=4)
    return data["users"][user_id]["points"]

@bot.command()
async def give(ctx, member: typing.Optional[discord.Member]=None, points:typing.Optional[int]=None):
    if not member:
        member = ctx.author
    if not points:
        points = random.randint(10, 50)

    # Have a separate getter for the points - this was just for the sake of concise code
    total_points = add_points(member.id, points)
    await ctx.send(f"Successfully gave {member.mention} {points} points! Total: {total_points}")

如有需要，我很乐意澄清。
