No it retuirns the filename. It is a string. Exactly like you would 
get
from raw_input() in a command line application. It has no "mode",
it is just a string. It is up to you to open the file in whatever mode
you require.

Thats because their functionality is pretty shallow. They open
a dialog box and return a filename, directory name or
an open file depending on which function you call and which
button you press. There is not much you can do with them
other than specify the starting folder and the title of the dialog!

Lundh has a couple of pages on them.

http://www.pythonware.com/library/tkinter/introduction/standard-dialogs.htm

And the Tk man pages give the official documentation
but in native Tcl.- but its not hard to translate if you've read
Lundh's intro.
