Discord.py-创建类别（如果不存在）

Question

如果类别不存在，我正在尝试创建一个类别。我曾尝试通过数据库进行此操作，但问题是我无法在该类别内创建文本通道，或者无法获取类别的ID，因为它位于元组而不是int。

因此，每当我对表情符号做出反应时，它将在TEXT-CHANNEL上由机器人创建的类别on_reaction_add()中创建一个APPLICATIONS，这是我当前的代码：< / p>

您可以使用discord.utils.get查找指定的类别

    guild = ctx.guild

    category = discord.utils.get(guild.categories, name='NAME')

    if category is None: #If there's no category matching with the `name`
        await guild.create_category('NAME') #Creates the category

    else: #Else if it found the categoty
        await ctx.send('Found') #Dosent make the category, instead it pass the creation of the category
