python - Short form to return method result if condition passed -

i'm wondering if there's pythonic or short-form method achieve following:

    error_response = self.check_conditions(request)     # if have error response, return it, otherwise continue normal.     if error_response:         return error_response 

something like:

(return self.check_conditions(request)) or pass 

alternatively, possible function return calling method, such as:

self.check_conditions(request)  def check_conditions(self, request):     error_response = do_stuff()     if error_response:         return_parent error_response 

i feeling second concept breaking ton of programming laws prevent chaos , apocalypse, thought though :)

no, there no short form conditional return.

but, second part of question:

there exceptions in python. can write this:

class myerrorresponse(exception): pass  class myclass:     ...     def check_conditions(self, request):         error_response = do_stuff()         if error_response:             raise myerrorresponse(error_response)      def do_the_main_stuff():         try:             self.check_conditions()             ...         except myerrorresponse e:             return e.args[0]
