Flask Create global response function to be called from every where in the web app - umen - Apr-14-2020

new to flask , i have web app that containes few parts
for example:

    utils/ 
    -- utils.py
    db/ 
    -- oracle.py 
    main.py

My Question is how can i make global_response function/handler that can be called from : utils.py,oracle.py,main.py without threading problem
for example:
in utils.py

 clas Utils():
      def A(self):
         return global_response("error","a")

oracle.py

 clas Utils():
          def ORA(self):
             return global_response("error ora","b")

main.py

def some_fun(self):
        return global_response("error main","c")

and here is the response function which was in main.py but now needs to be called from any where :

 def global_response(error_msg, title,*options):
        res = {"status": error_msg, "title": title}
    
        for option in options:
            res.update(option)
       
     return json.dumps(res)
