Now that we're finished with the form, we need a way to retrieve data from it so it can be processed by the application. We'll create a method that returns a dictionary of the form's data and, as we did with our LabelInput objects, maintain the Tkinter convention of calling it get().
Add the following method to your form class:
def get(self): data = {} for key, widget in self.inputs.items(): data[key] = widget.get() return data
The code is simple: we loop through our instance's inputs object containing our LabelInput objects and build a new dictionary by calling get() on each variable.
This code demonstrates the power of both iterable objects and consistent naming schemes. If we had stored our inputs as discrete ...
