Hi, if I have certain run time conditions to check before defining some upstream tasks, can I still use the same task variable for dependencies?

```if condition:
	task_A = run_task_a()

run_task_b(upstream_tasks[task_a]). # &lt;-- will this work? ```


or would I need to do this?
```if condition:
	task_A = run_task_a()
    run_task_b(upstream_tasks[task_A])

else:
	run_task_b()```

Hi <@UPV0FJA3D> - thanks for the question!  I guess the question depends on whether you want run_task_b to always run.  The <https://docs.prefect.io/core/concepts/execution.html#triggers|docs on triggers> should give you a bit more information and background on when things will run or not.
