Could you elaborate your example here? Basically, this type of error checking does not look familiar to me in Python code. In C when one works with descriptors and has to check status codes after every call it looks natural. Maybe I just haven't used it this way, so I'd really appreciate a more specific use case. -- https://mail.python.org/mailman/listinfo/python-list
