If you know what settings you need, you can just use the cget
method to get values e.g.
from Tkinter import *
root = Tk()
w = Label(root, text="Hello, world!")
w.pack()
print w.cget('text')
root.mainloop()
It will print
Hello, world!
If you want to know all the available options, widget.config contains the config and from that if you wish you can create all or a subset of settings which you may need e.g.
import pprint
from Tkinter import *
root = Tk()
w = Label(root, text="Hello, world!")
w.pack()
pprint.pprint(w.config())
root.mainloop()
