By using 'yield', you > get Python to generate all the class boilerplate for you. I think the OP can learn from the comparison. One question, many lessons: * Here's how you write a generator. * Here's how you write a context manager class. You run into those quite often as well. * See how much more suitable a generator is in this case. No need to shoot down those who only try to be helpful. Marko
