A variable is global so long as you have not assigned it a value in your function. The latter makes the variable local. Even if, like in your case, the condition is not satisfied.
Note: The use of global variables is discouraged.
I suggest you modify your code as below:
def execute_query(query_to_execute, *args, **kwargs): paths = kwargs.get('paths', {}) queries = {'postgresqlVersion': '''{{postgresqlVersion}}''','entityRelationships': '''{{entityRelationships (entity: "{}") {{name}}}}''','path': '''{{path(name: "{}", path: "{}", annotate: "{}")}}''','path_step': '''{{pathStep(name: "{}", step: "{}", key: {})}}''' } schema = graphene.Schema(query=Query) #schema.execute('''{path(name: "Ventas", path: "general_state/general_city/inventory_store/operations_sale", annotate: "_count")}''') result = schema.execute(queries[query_to_execute].format(*list(kwargs.values()))) dict_result = dict(result.data.items()) return {'top': dict_result, 'full': paths}If you insist on having the paths as a global variable, you can take the following approach (using the variable, but, not assigning to it)
paths = {}....def execute_query(query_to_execute, *args, **kwargs): new_paths = kwargs.get('paths', paths) queries = {'postgresqlVersion': '''{{postgresqlVersion}}''','entityRelationships': '''{{entityRelationships (entity: "{}") {{name}}}}''','path': '''{{path(name: "{}", path: "{}", annotate: "{}")}}''','path_step': '''{{pathStep(name: "{}", step: "{}", key: {})}}''' } schema = graphene.Schema(query=Query) #schema.execute('''{path(name: "Ventas", path: "general_state/general_city/inventory_store/operations_sale", annotate: "_count")}''') result = schema.execute(queries[query_to_execute].format(*list(kwargs.values()))) dict_result = dict(result.data.items()) return {'top': dict_result, 'full': new_paths}
