How do you retrieve the results from an `ifelse`? Thanks

anytime you _call_ a task using the functional API, a task copy is made.  So in this case, you’d want to capture the return value of `ifelse(...)` so you can reference it later:
```
ifelse_return = ifelse(...)
```
and then after your flow has ran:
```
flow_state = flow.run()
flow_state.result[ifelse_return].result
```

Yeah I was not clear.  In the `flow` I need the result of a branch to feed to the next task in that branch.

ah i see; yea check out <https://docs.prefect.io/core/tutorials/task-guide.html#adding-tasks-to-flows> on when task copies get made; in this case you’d do:
```
true_upstream = true_task(y)
ifelse(check_task(x), true_upstream, false_task(z))

second_true_task.set_upstream(true_upstream, key="arg1")
# or second_true_task(arg1=true_upstream)
```
