Parameters prompt: string Prompt to display to the user. message: string, optional Message to display under the entry line. formats: list of strings, optional The formats that the user can enter dates in. These should be format strings as accepted by the datetime.datetime.strptime() function from the standard library. They are tried in order, and the first that returns a date object without error is selected. Note that the '%x' in the default list is the current locale's date representation. show_example: Boolean If True, today's date in the first format given is appended to the message. Returns ------- datetime.date, or None if the dialog is cancelled. """
