Hi Steve,

you can use the option: 'defaultextension'. Example

>>> import tkFileDialog
>>> res = tkFileDialog.asksaveasfilename(defaultextension=".txt")
(user types in "myfilename")
>>> res
'myfilename.txt'

Remember the dot in the extension string. I just tried and it works, unless the user selects a filename that already exist.
