Question

您好，当它出错时，我希望它为发生错误的服务器自动创建文件夹

def get_prefix(client, message):
    with open(f'Data/{message.guild.id}/settings.json', 'r') as f:
        prefixes = json.load(f)
    
    return prefixes['prefix']

client = commands.Bot(command_prefix=get_prefix, case_insensitive=True)

使用try，except，如果出现任何错误，我们就可以运行一段代码[....] 当公会已经有了settings.json时，它将返回前缀！否则，它将为该行会创建一个新的settings.json。请注意：为data字典设置一些值！将一些值存储到创建的settings.json

中

def get_prefix(client, message):
    try:
        with open(f'Data/{message.guild.id}/settings.json', 'r') as f:
            prefixes = json.load(f)
        return prefixes['prefix']
    except:
        data = {'prefix':'!'}#data is dict to save something on it
        with open(f'Data/{message.guild.id}/settings.json', 'w') as f:
            json.dump(data, f)
        return data['prefix']
client = commands.Bot(command_prefix=get_prefix, case_insensitive=True)

如果get前缀有错误，则自动创建文件
