how to pass a variable to a function?

[Jormono1]

Hello, I am trying to setup a program to do receive data via bluetooth from my computer, it may or may not be too much data for the hub to hold all at once on top of the code telling the hub what to do with the data. So my first thought is to define functions and pass arguments/parameters through my function call but this doesn't seem to do anything at all (see example)

from pybricks.hubs import CityHub
from pybricks.pupdevices import Motor
from pybricks.parameters import Direction, Port, Stop
from pybricks.tools import multitask, run_task, wait

hub = CityHub()
X_Motor = Motor(Port.A, Direction.CLOCKWISE)
Y_Motor = Motor(Port.B, Direction.CLOCKWISE)

async def main():
    
    def test_function (x_coord, y_coord):
        await multitask(
            X_Motor.run_target(500, x_coord, Stop.COAST),
            Y_Motor.run_target(500, y_coord, Stop.COAST))
    
    test_function(800, 390)
    wait(1000)

run_task(main())

My plan is for the data stream to include coordinates for X, Y, and Z motors that can be passed directly into the run target function but either I'm doing something wrong here or it doesn't work the way I expect it to.

from pybricks.tools import multitask, run_task, wait

hub = CityHub()
X_Motor = Motor(Port.A, Direction.CLOCKWISE)
Y_Motor = Motor(Port.B, Direction.CLOCKWISE)

async def test_function(x_coord, y_coord):
    await multitask(
        X_Motor.run_target(500, x_coord, Stop.COAST),
        Y_Motor.run_target(500, y_coord, Stop.COAST))

async def main():
    await test_function(800, 390)
    await wait(1000)

run_task(main())

All functions that await need to be async and all functions that are async need to be awaited.

run_task() and multitask are special in that they take care of the awaiting, so we don't use the await keyword with the async functions that are called there.
