How to use returned list from function, as function args in Python

Question

    @property
    def randomcolours(self):
        return [int(x * 255) for x in colorsys.hsv_to_rgb(random.random(), 1, 1)]

    @tasks.loop(seconds=3, count=15)
    async def rainbow_embed(self, _, t, d):
        await self.bot.ini.edit(embed=discord.Embed(title=t, description=d, colour=discord.Colour.from_rgb(*self.randomcolours())))

I am trying to pass the 3 returned values from randomcolours as the arguments in the colour kwarg but I am getting a TypeError: 'list' object is not callable , how can I do this?

Answer 1

randomcolours is a @property , so an expression like self.randomcolours will call the function and evaluate to the list. Thus, when you call it like self.randomcolours() , you're actually calling the list returned from the property. It's not possible to call a list, so you get the error.

How to solve:

• don't call the list: discord.Colour.from_rgb(*self.randomcolours)
• or don't make randomcolours a property
