*Python*

Use the tkinter module and the tkinter.ttk submod- ule to create a simple flashcard application. 1. Create a subclass of the Tk class for the file-loading window. This window should appear when the application is first launched. This window should have: (a) text that describes what the app is (give it a name)

(b) a text-entry box where you can type in the name of a text file (which will contain the flash card data). There should be enough information in the window that the user knows that this is the box for entering the filename.

(c) a button that, when clicked, will load the given text file and open up a separate window for displaying the cards. It should be clear to the user what will happen when they click the button. If there is no such file, or if an OSError occurs while trying to open the file, your application should display an error message to the user asking them to try a different filename.
