??? Your question unfortunately doesn't make a lot of sense to me. A cache for what? I suspect you are operating under an assumption which seems to make sense to you, but isn't actually correct. I think, if I were to answer your literal question, I would say "No", the Python shell doesn't have a cache. But the Python compiler has all sorts of caches, regardless of whether it is running in the shell or not. It caches modules. It caches all sorts of objects. But this shouldn't be a problem under normal circumstances. My guess is that it isn't a cache that is causing problems, but a misinterpretation of what you are seeing. But I could be wrong. Can you explain in detail what you mean by "when I do lots of modifications within a program", "runtime errors", and especially what you mean by calling the program "clean"? How are you making modifications to the program? How then do you see the errors? ... let me think... are you using reload()? Because that doesn't work like you might be thinking. When you reload a module, it doesn't affect objects which are already in use. Likewise with importing. But since I don't know how you are making modifications, or what you are doing that generates runtime errors, I can't tell what you're doing wrong. Oh, wait, I see you are using Python 3.0. Don't. Python 3.0 is not supported because it is buggy. You should use 3.1, or better still, 3.3. Python 3.3 is much better than 3.1 or 3.2, and 3.0 is buggy and slow. -- Steven _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
