Tkinter:select directory dialog?

[Park997]

Hi,
I have written an application that reads in several data files located in a
single directory. Currently the directory is hard coded in a module as a string
variable. On other computers, the data may be located in other directories. Is
there a Tkinter dialog for choosing a directory, but not picking a file to open
or write to? An entry field could be OK, but that would involve typing in a
path, and probably validity checking, etc. A nice graphical "choose a
directory"  Dialog would help. Does such a thing exist?

Thanks,
