WebNov 24, 2024 · Once we have those up and running, we’ll need to install a few python packages that we’ll use to setup a web server (Flask) and have cleaner bindings between GraphQL and SQLAlchemy (Graphene, Graphene_SQLAlchemy), so run python3 -m pip install flask flask_graphql sqlalchemy graphene graphene_sqlalchemy, if you don’t have … Webimport graphene class Character(graphene.ObjectType): appears_in = graphene.List(graphene.String) Lists work in a similar way: We can use a type modifier to mark a type as a List, which indicates that this field will return a list of that type. It works the same for arguments, where the validation step will expect a list for that value.
