File Dialogs
The tkFileDialog module can be used to get a filename from the user. The module provides two convenience functions, one to get an existing filename so you can open it, and one to get a new filename, to save things into.
tkFileDialog.askopenfilename([options]). If the dialog is cancelled by the user, the function returns None.
tkFileDialog.asksaveasfilename([options]).
