Discord.py if 语句不起作用

Question

我有这段代码（Python 3.6），它应该这样做，如果用户有一个钱包，然后显示余额。如果他们没有钱包，请创建一个钱包并出示余额。

我有一个名为 amount.json 的文件，其中包含用户 ID。

代码总是跳转到它说用户没有帐户的语句，而实际上我有，并给我错误：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: BlockIoAPIError: Failed: Label already exists on your account for Network=DOGE.

我该如何解决它，使它不会在我每次执行余额命令时都尝试制作钱包？

代码：

@client.command(pass_context=True)
async def balance(ctx):
    user_id = ctx.message.author.id
    global amounts
    if user_id not in amounts:
        block_io.get_new_address(label=user_id)
        knee = block_io.get_address_balance(label=user_id)
        s1 = json.dumps(knee)
        d2 = json.loads(s1)
        d2['data']['available_balance']
        embed=discord.Embed(description="Bitcoin: btc here \n\nLitecoin: here\n\nDogecoin: {}".format(d2['data']['available_balance']), color=0x00ff00)
        await client.say(embed=embed)
        with open('amounts.json', 'w+') as f:
            json.dump(amounts, f)
    elif user_id in amounts:
        knee = block_io.get_address_balance(label=user_id)
        s1 = json.dumps(knee)
        d2 = json.loads(s1)
        d2['data']['available_balance']
        embed=discord.Embed(description="Bitcoin: btc here \n\nLitecoin: here\n\nDogecoin: {}".format(d2['data']['available_balance']), color=0x00ff00)
        await client.say(embed=embed)
        with open('amounts.json', 'w+') as f:
            json.dump(amounts, f)

Json 代码：

amounts = {}
@client.event
async def on_ready():
    global amounts
    try:
        with open('amounts.json') as f:
            amounts = json.load(f)
    except FileNotFoundError:
        print("Could not load amounts.json")
        amounts = {}

您需要对您的 json 文件进行数据修复，使其具有您的代码所期望的结构。如果有重复的条目，下面将对它们的值求和。这不是你的机器人的一部分，你应该只需要运行一次。您还需要查看任何其他涉及或依赖amounts的代码

import json

with open('amounts.json') as f:
    old_amounts = json.load(f)

new_amounts = {}
for d in old_amounts:
    for k, v in d:
        new_amounts[k] = new_amounts.get(k, 0) + v

with open('amounts.json') as f:
    json.dump(new_amounts, f)

那些d2 = json.loads(s1) 行应该是d2 = json.load(s1)
