Couchbase Python Lookup_in Question

Couchbase Server

Data Example

{
“userId”: 1,
“firstName”: “AAAAA”,
“lastName”: “as23”,
“phoneNumber”: “123456”,
“emailAddress”: “AAAAA@test.com”,
“homepage”: “https://aaaaaa.aaaaa.com/1”
}

I want to select firstName, lastName, phoneNumber only. Through Python SDK lookup_in

res = collection.lookup_in(key, (SD.get(“firstName”), SD.get("lastName), SD.get("phoneNumber)))

This possible to make a choice in the a way?
