Yes. Try to paste only the relevant parts, or, if possible, post a small self-contained example that can be run by the reader without further editing. > Is there another?

In your case: > New_Specs = [] for item in ThisList: > DataLine, Spec = GetLineByItem(item) ... > NewSpec = tk.StringVar() > New_Specs.append(NewSpec) Now, as you need DataLine later-on why not keep a copy? So let's turn New_Specs into a list of StringVar, DataLine tuples: > New_Specs = [] for item in ThisList: > DataLine, Spec = GetLineByItem(item) ... > NewSpec = tk.StringVar() New_Specs.append((NewSpec, DataLine)) When the function terminates (there is a mainloop() missing) you can create and return the result: # long form, with a loop result = [] for spec, dataline in New_Specs: result.append(dataline + " " + spec.get()) return result # alternative using a listcomp: return [dataline + " " + spec.get() for spec, dataline in New_specs] -- https://mail.python.org/mailman/listinfo/python-list
