That's true when the functions are declared at the outer level of the module, but don't overlook the fact that a function can be declared inside another function or method call (and even returned as (part of) the result of that call). It would be more accurate to say that the default argument values are bound when the def statement is executed. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://holdenweb.blogspot.com Recent Ramblings http://del.icio.us/steve.holden -- http://mail.python.org/mailman/listinfo/python-list
