~Output doesn't have a `concat` method~
My apologies, it would seem that is has one in python, but it won't do what you want it to do.

`Output` <https://www.pulumi.com/docs/intro/concepts/inputs-outputs/#f4eb8a2d-16c1-4f8d-a278-12868110528c:~:text=url%20%3D%20Output.concat(%22http%3A%2F%2F%22%2C%20hostname%2C%20%22%3A%22%2C%20port%2C%20%22%2F%22)|does have> a `concat` method, in python. However, `concat` also returns an `Output`, and I’m guessing you’re trying to `print` the result of the `concat` - is that right?

<@U01CPE961M2> you might find the following thread helpful, it’s addressing typescript (and `interpolate` is the typescript version of `concat`) - but the underlying concepts are the same: <https://pulumi-community.slack.com/archives/C84L4E3N1/p1617752754269000>

I have tried to use the `.apply method but no success`

If you are trying to print the string you will have to do that within the apply

Might be easier to help if you give us a code sample

It is not a `print` as in function but an expansion to  string

Thanks for the reply. I will try the suggestion on the issues
