Sounds like what you want to do is subclass Button:

# probably won't work as I'm doing this off the
# top of my head, but you get the picture

from Tkinter import *


class b_Button(Button):
    def __init__(self, r, myName):
        self.myName = myName
        Button.__init__(self, r, text=myName, command=self.introduceMyself)
    def introduceMyself(self):
        print "Hello, from button", self.myName

root = Frame()
root.pack()

for b in ("shoes", "ships", "sealing-wax", "cabbages", "kings"):
    b_Button( root, b).pack()
    
root.mainloop()
