Hello
There are several different objects. However, they all share the same function.
Since they are not the same or similar, it's not logical to use a common superclass.
So I'm asking, what's a good way to allow those objects to share that function?
The best solution I've found so far is to put that function in a module, and have all objects import and use it. But I doubt that's a good use-case for modules; writing and importing a module that contains just a single function seems like an abuse.
Thanks, Xif
Could you give an example?

Sure, I can describe my particular case.
It's a program that retrieves / updates Microsoft Excel spreadsheet data.
There are two major classes:
1) an Excel class, that represents of the whole Excel program 2) a Cells class, that abstracts retrieval and editing of cells.
Both classes use a function called getCells() as part of their __getitem__() methods.
getCells() parses the __getitem__() call arguments, and returns an iterator over the appropriate cells.
The difference between the 2 classes is that a Cells instance just converts the generator into a list and returns it:
#<code> return list(getCells(self.sheet, cells)) #</code>
while an Excel instance returns the values of the cells:
#<code> return [cell.Value for cell in getCells(self.sheet, cells)] #</code>
As you can see, both use the getCells() function.
So my question is, where is the best way to put it so instances of both classes can use it?
