Make zd an instance variable instead: this even allows you to have
multiple instances which won't interfere with each other.

        def viewDict(self):
                new = Toplevel()
                self.zd = ScrolledText(new, height = 30, width = 70)
                self.zd.pack(fill=BOTH, expand=YES)
                self.zd.insert('0.0', open('c:/mytools/mydict.py', 'r').read())
                Button(new, text='Save', fg='red',
command=self.saveDict).pack()

        def saveDict(self):
                contents = self.zd.get(1.0, END)
                output = open('c:/mytools/mydict.py', 'w')
                output.write(contents)
                output.close()
