Hi David, It's possible to make dynamic callbacks. For example: ###### >>> def some_function(x): ... print "I see", x ... >>> def make_callback(n): ... def callback(): ... return some_function(n) ... return callback ###### make_callback() is a function that returns a "thunk" callback. That returned thunk doesn't take an argument, so it's perfectly appropriate as a button callback. And yet, that callback can remember what was initially passed into make_callback() --- it remembers the datum that we used to build the thunk. Here, take a look: ###### >>> callbacks = [make_callback(i) for i in range(5)] >>> callbacks[0] <function callback at 0x403a610c> >>> callbacks[0]() I see 0 >>> callbacks[1] <function callback at 0x403a6bfc> >>> callbacks[1]() I see 1 ###### Does this make sense? Please free to ask questions about this. Good luck! _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
