import graphene

class Query(graphene.ObjectType):

    def resolve_hello(self, info):
        return 'World'

schema = graphene.Schema(query=Query)

        query SayHello {
          hello

    result = schema.execute(query)

    print (result)

@nojvek This happens because you've got a file named "graphql.py" and so Python uses that instead of the graphql-core module that Graphene depends on. Renaming your file to something else should fix it.
