Question

我收到的行语句无效，除了：来自此代码......

from .utils.dataIO import fileIO
from .utils import checks
from __main__ import send_cmd_help
from __main__ import settings as bot_settings
import discord
from discord.ext import commands
import aiohttp
import asyncio
import json
import os

class Transformice:
    """Transformice"""

    def __init__(self, bot):
        self.bot = bot

    @checks.is_owner()
    @commands.group(name="tfm", pass_context=True, invoke_without_command=True)
    async def tfm(self, ctx):
        """Get Transformice Stats"""
        await send_cmd_help(ctx)

    @checks.is_owner()
    @tfm.command(pass_context=True)
    async def mouse(self, ctx, *name):
        """Get mouse info"""

        if name == ():
            mouse = "+".join(name)
            link = "http://api.micetigri.fr/json/player/" + mouse
            async with aiohttp.get(link) as r:
                result = await r.json()
                name = result['name']
                msg = "**Mouse:** {}".format(name)
                await self.bot.say(msg)
        except:
                await self.bot.say("Invalid username!")

def setup(bot):    
    n = Transformice(bot)
    bot.add_cog(n)

有人可以解释我为什么会收到此错误以及如何解决此错误。我对python中的一些错误以及如何修复它感到困惑。

Answer 1

except子句仅在try块之后才有意义，并且没有。看起来你不是在寻找异常处理，而只是一个else子句。

无论

try:
    code_that_might_fail()
except ValueError:
    print("ouch.")

或

if condition:
    do_this()
else:
    do_that()

Answer 2

你应该放一个

try-except阻止在你的代码中。您仅使用except block ...否try声明。

   try:
        if name == ():
            mouse = "+".join(name)
            link = "http://api.micetigri.fr/json/player/" + mouse
            async with aiohttp.get(link) as r:
                result = await r.json()
                name = result['name']
                msg = "**Mouse:** {}".format(name)
                await self.bot.say(msg)
    except:
            await self.bot.say("Invalid username!")

如果错误只是因为except语法，你应该使用上面的内容。或者您可能希望使用else:并使用except

来自除外的语法无效
