Python - open（）不起作用

#BLACKLIST PROFILE CREATION COMMAND
@bot.command(pass_context=True)
async def blacklist(ctx, removeoradd, user: discord.Member, *, reason):
    if ctx.message.author.id == developerID:

            blacklist.write("{}".format(blacklist_template))

            blacklist.close()

            embed = discord.Embed(title="Admin Control", description="Blacklisted:\n``{}/{}``".format(user.name, user.id))

            embed = discord.Embed(title="You can no longer create a profile.", description="If you think this is a mistake do {}appeal <reason>".format(prefix))

  File "run.py", line 126, in blacklist
blacklist = open(os.path.expanduser("/Blacklisted/{}.json".format(ctx.message.author.id)), "x")
FileNotFoundError: [Errno 2] No such file or directory: '/Blacklisted/182288858782629888.json'

所以基本上我试图用blacklist_template内容创建一个文件。我认为当你使用＆＃34; w＆＃34;模式，它为您创建一个新文件。我做错了什么？
