modular programming problem

[kakarukeys]

my code has a number of classes, each of them have its own methods to communicate with users, via a console or GUI.

Is it possible to group the methods of the same type into a module, so that, according to user preference, the program may communicate with users via a console or GUI by importing the correct module that contains all the methods (either console or GUI) for the classes?

Well, if I understand your question, lets say you have two modules, first is name consoleUI.py and second is name GUI.py, in your main program, you just do:

if user_pref_ui=="c":#"c" for console
  import consoleUI as UI
if user_pref_ui=="g":#g for graphical:
  import GUI as UI

Of course both module need to have the same function names, so during your main program you just call lets say UI.giveData(data), and each module handles the data its own way.

There is a twist, in my program I have already grouped the connected data and functions into objects. Each object has its own (using the example you gave) "giveData" method. I would like to group all such "giveData" methods across different objects into one module, so that, I could either import all "giveData" in consoleUI version or GUI version depending on user preference. Does Python allow this?

If I don't do this, each class will have to have two versions of "giveData" in the memory, consoleUI and GUI.

hmm... I don't really understand. But I would answer:

from module import Object1,Object2,...

and If you want to change the names:

from module import obj1 as name1,obj2 as name2, obj3 as name3,etc...

It will only load these specific objects in memory.

Here is one way I can think of:
Is there a better way?

a.py

def giveDataA(self, x): #method of Class A
	return x**2
def giveDataB(self, x): #method of Class B
	return x**3
giveData = [giveDataA, giveDataB]

b.py

def giveDataA(self, x): #method of Class A
	return x**4
def giveDataB(self, x): #method of Class B
	return x**5
giveData = [giveDataA, giveDataB]

main.py

user_pref_ui = input()

if user_pref_ui=="a": #choose A
  import a as UI
if user_pref_ui=="b": #choose B
  import b as UI

class A:
    def __init__(self):
        self.var = 5
    giveData = UI.giveData[0]

class B:
    def __init__(self):
        self.var = 10
    giveData = UI.giveData[1]

Oa = A()
Ob = B()
print(Oa.giveData(Oa.var))
print(Ob.giveData(Ob.var))
