I would like to produce some custom output with python with data from Tableau files. I don't have access to the Tableau server to run the 'Tabpy' library.
Is there any other way to do it?
I think you're on the wrong site. This site is dedicated to Qlik products. Tableau has its own very active community site at https://community.tableausoftware.com where the Tableau experts will be more than happy to help you.
