It's as though you had "PyObject txt;" at the top of the function. The scope is the function. There's no way (afaik) to make a variable be local to a portion of the function - that's a feature that has to be sacrificed to the simplicity of not declaring variables. In my opinion it's better to declare them, except in interactive code (eg IDLE or just typing "python"). But Python isn't that. Chris Angelico -- http://mail.python.org/mailman/listinfo/python-list
