Discord.py 禁用模块命令

Question

I made a "disable module" which is working, but when it loads into a json file I get a error message.

@client.command(aliases=["disable economy"])   
async def disable_economy(message): 
    with open('disable economy.json', 'r+') as f:
        channel = json.load(f)
        if not f'{message.channel.id}' in channel:
            channel[f'{message.channel.id}'] = "Channel ID"
            json.dump(channel, f)
            await message.channel.send(f"Economy has been disabled in <#{message.channel.id}>. ")
            return
        if f'{message.channel.id}' in channel:
            await message.channel.send("Economy is already disabled in this channel.")
            return

After doing the command it loads into a json file like this: {}{"750485129436201023": "Channel ID"} and the error message I get is: End of file expected . The error is between the 2nd {. Can someone help?

{}{"750485129436201023": "Channel ID"} is not valid JSON.

Valid JSON can only have one root element, such as {}

Change your JSON file to just:

{"750485129436201023": "Channel ID"}

Python is appending to the file, instead of overwriting it, the easiest way to fix this is to seek to the beginning of the file before writing:

f.seek(0)
json.dump(channel, f)
