Question

I have various classes Class1, Class2, Class3, etc. all of which contain this exact piece of content inside:

def showName(self):
   openWindow()
   print self.name

For example:

class Class1:
    # SOME CODE

    def showName(self):
       openWindow()
       print self.name

    # SOME MORE CODE

What is the best way to have showName defined once in a separate file and import it back to Class1, Class2, Class3, etc.?

Answer 1

Derive from this mixin:

class NameShowMixin(object):
    def showName(self):
        openWindow()
        print self.name

Or make it a separate function, in case you intend name to be a public member.
