Tkinter is a very thin wrapper over an embedded tcl/tk interpreter. So I
guess the API change is caused by a tcl/tk version change, not by a Python
one. You can check the version of the tcl/tk interpreter you're using from
Python via:
root = Tkinter.Tk()
root.tk.eval('puts $tcl_patchLevel')
root.tk.eval('puts $tk_patchLevel')

I'd use this way:
import tkFont
entryFontDescr = Entry()["font"]
entry_font = tkFont.Font(font=entryFontDescr)
print entry_font.actual()
