Can't pass multiple arguments to function in Python-CodePudding

It doesn't let me pass multiple arguments to my function. Python keeps thinking I'm still defining the first argument. The code:

async def find(ctx, user, parachannel):
    user = int(user)
    parachannel = int(parachannel)
    funchannel = bot.get_channel(parachannel)
    fun_guild = bot.get_guild(880108797820026881)
    memberuser = fun_guild.get_member(user)
    fun_calc = 0
    async for message in funchannel.history(limit=10):
        if message.author == memberuser:
            fun_calc = fun_calc   1
    return fun_calc


gen_calc = find(user, 880123663318409277)
print(gen_calc)

Getting this error:
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: find() missing 1 required positional argument: 'parachannel'

CodePudding user response：

find(ctx, user, parachannel) function requires 3 arguments: ctx, user and parachannel. But when you call the function you're only giving two arguments. ctx = user and user = 880123663318409277. You're missing the 3rd argument parachannel.

CodePudding user response：

Your function requires three arguments but you only pass two to it. So, naturally you see an error. You should give your parameters some default values. For example something like this:

async def find(ctx = None, user = "Mushtaq", parachannel = 0):
    user = int(user)
    parachannel = int(parachannel)
... and the rest of your code.

CodePudding user response：

If it's not necessary to keep ctx as first argument, you can do

async def find(user, parachannel, ctx = None):
    # You codes
    return fun_calc

Now you can call your function without ctx argument.

gen_calc = find(user, 880123663318409277)
