I think you need to create the City class (if not yet existing), and then to create City individuals:

        onto.City(name = "Bamberg")http://owlready2.readthedocs.io/en/latest/class.html

See the documentation of Owlready2 here :

        http://owlready2.readthedocs.io/en/latest/class.html

You can list city individuals with: onto.City.instances()

Thankyou for your reply ... one more question can instead of bamberg can it be a variable ? that changes values all the times

Hello,

Yes, it can be a variable :

                onto.City(name = city_name_variable)

Hello. How may I create subclasses using a variable? For example:
class name is favorites

fruits = [apple, orange, grapes]

for x in fruits:
   add x as subclass of the class favorites

Thank you.

[Joe S.]

Figured out how to add subclasses using a variable.

fruits = ["orange", "apple", "peach"]

for x in fruits:
        types.new_class(x, (onto["Food"],))

This adds "orange" , etc., as subclasses to the superclass "Food".
