Sure you can, just use a lambda expression. Here is
an example which shows an 'activate' callback (button
command) and a MB1 binding. Note that the binding 
has to allow for the event object:

from Tkinter import *

def prtIt(text):
    print text

root = Tk()

Button(root, text='B1', 
       command=lambda arg='Button 1': prtIt(arg)).pack(side=LEFT)

b2 = Button(root, text='B2')
b2.pack(side=LEFT)
b2.bind('<Button-1>', lambda e,arg='Button 2': prtIt(arg))

root.mainloop()
