The function is compiled when the module is compiled. At latest that is when the module is imported (though in most cases it was probably compiled the first time you ran the code and isn't recompiled unless the source code changes). The default parameters are actually evaluated when the 'def' statement is executed and the function object is created from the default arguments and the previously compiled code block. -- Duncan Booth http://kupuguy.blogspot.com -- https://mail.python.org/mailman/listinfo/python-list
