How to use

Output

on a Python list? Here's the sudo code:

sns_topics: list[Output] = create_sns_topics()
receivers = []
for topic in sns_topics:
    receiver = {
        "arn": topic.arn
    }
    receivers.append(receiver)

yaml.dump(receivers)

yaml.dump

throws because it cannot handle future objects (from

topic.arn

). I went through the doc on Outputs, but couldn't quite figure out how to use

.apply

on a list
