Hi @Marvin How can flatten out a list of list contain

PrefectFuture

objects, without raising a

TypeError: 'PrefectFuture' object is not iterable

To flatten a list of

PrefectFuture

objects, you'll want to ensure you're handling them correctly without trying to iterate over them directly since they aren't inherently iterable. The

PrefectFuture

class provides methods to manage asynchronous task execution, but if you have a list of lists containing these objects, you can flatten them using a simple list comprehension. Here's a basic approach to flatten such a list:

python
# Suppose `list_of_lists` is your list of lists containing PrefectFuture objects
flattened_list = [future for sublist in list_of_lists for future in sublist]

This comprehension will iterate over each sublist and then over each

PrefectFuture

object within those sublists, effectively flattening the structure. You can find more about

PrefectFuture

and related utilities in the Prefect source code. If you need to wait for all the futures to complete, you might want to explore methods provided by the

PrefectFuture

class, such as

result()

or

wait()

. If you encounter any issues, feel free to provide more details, and I can assist further.
