interrupt multitask

[ytraub]

Whats a good way to interrupt multitask functions?

From inside the function, you can just return. From outside of the function, you can call task.close().

You can also do multitask(task1(), task2(), race=True) where one task finishing will cause the other task to be canceled.

There is also a bit about cancellation in https://github.com/orgs/pybricks/discussions/356.

What do you mean with task.close()? What is "task" in that case?

[dlech]

A Task object or a coroutine. This is the value returned by calling an async function.

t1 = task1()
t2 = task2()
await multitask(t1, t2)

is basically the same as

await multitask(task1(), task2())

Except now you have variables with the task objects. So you can call t1.close() to cancel that task.
