Question

所以我遵循了这个 youtube 教程，并做到了这一点"

@client.command()
@commands.cooldown(1, 6.0, commands.BucketType.user)
async def work(ctx):
    await open_account(ctx.author)
    
    users = await get_bank_data()
    
    user = ctx.author
    
    earnings = random.randrange(1000)
    
    await ctx.send(f"You worked on cleaning a toilet, got yourself covered with toilet water and poo, but you managed to get $ `{earnings}`")
    
    wallet_amount = users[str(user.id)]["Wallet"] + earnings 
    
    with open("bank.json", "w") as f:
        json.dump(users,f)

这曾经有一个 "+="，但它不起作用，我的朋友说它会像 x = a + x，这是有道理的，我决定把它变成一个 +，但是，现在它不会添加收入金额。我需要改变什么？我的很多其他类似的代码都有同样的问题。

编辑：

似乎 json 将字典中的整数键作为字符串保留，所以我不得不将 str() 放回 users[str(user.id)]

我无法测试您的代码，但它应该只需要

users[str(user.id)]["Wallet"] += earnings

但是这个user.id在users中可能不存在所以你应该检查它并使用0创建钱包

if user.id not in users:
    users[str(user.id)] = {"Wallet": 0}
    
users[str(user.id)]["Wallet"] += earnings

问题也是您在 get_bank_data() 中所做的，因为它会为 users = ... 赋值，并且它可能会替换数据并且可能会删除新值。

使用命令 !work 和 !wallet 的最小工作示例。

如果它在开始时找不到 bank.json 则创建它。

from discord.ext import commands, tasks


TOKEN = os.getenv('DISCORD_TOKEN')


client = commands.Bot(command_prefix="!")

async def get_bank_data():

    with open("bank.json", "r") as f:
         users = json.load(f)

    return users

@client.command()
@commands.cooldown(1, 6.0, commands.BucketType.user)
async def work(ctx):
    #user = ctx.author
    user_id = str(ctx.author.id)

    users = await get_bank_data()

    earnings = random.randrange(1000)

    await ctx.send(f"You worked on cleaning a toilet, got yourself covered with toilet water and poo, but you managed to get $ `{earnings}`")

    if user_id not in users:
        print('[work] Create wallet for:', user_id)
        users[user_id] = {"Wallet": 0}

    users[user_id]["Wallet"] += earnings

    with open("bank.json", "w") as f:        
        json.dump(users, f)

@client.command()
async def wallet(ctx):
    #user = ctx.author
    user_id = str(ctx.author.id)

    users = await get_bank_data()

    if user_id not in users:
        await ctx.send("You don't have wallet. Try !work")
    else:
        wallet_amount = users[user_id]["Wallet"]
        await ctx.send(f"You have $ {wallet_amount} in wallet")
    
# --- start ---

if not os.path.exists( "bank.json"):       
    print("[START] Create empty 'bank.json'")
    users = dict()
    with open("bank.json", "w") as f:
        json.dump(users, f)

client.run(TOKEN)
