Hi there — yes, in order to get at the underlying/resolved value, you’ll need to use

apply

as described here: https://www.pulumi.com/docs/intro/concepts/inputs-outputs/?language=python#apply

I thought that the result of the call to apply is another Output object?

Yes — the result of the call to

apply

is an

Output[T]

, but within the callback that’s passed to apply, you can work with the raw `T`:

Copy code

bucket = s3.Bucket('my-bucket')

def compare(a, b):
    if a == b:
        print("match")
    else:
        print("no match")

bucket.id.apply(lambda id: compare(id, "some-string"))

You can also do something like this, which can be a little nicer to work with:

Copy code

bucket = s3.Bucket('my-bucket')
some_known_value = "foo"

# Capture the result as an Output[bool].
is_match = bucket.id.apply(lambda id: id == some_known_value)

# Use its apply() to work with the result.  
is_match.apply(lambda m: print("Match!" if m else "No match."))

Okay thank you! I'll give that a shot
