Maybe. "get_track_length()" might be a reasonable method name for something that opens an audio file, reads its header, and returns its length in seconds. It should be a method rather than a property (attribute access should be fast), but "get" makes sense here, as it's not calculating or anything, it's just retrieving information. But yes, if it's a calculation, "calc" would be more common. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
