That's good advice. A typical refactoring technique when working with blob classes is to extract groups of methods with commmon functionality, put them in a helper class, make a helper object and pass it to the original blob. In other words, tp split the blob object as a composition of small logically independent objects. BTW, is there anybody in this lists that can suggest good books about refactoring in Python? There are plenty of books about refactoring for Java and C++ but on top of my mind I cannot think of a Python book right now. -- http://mail.python.org/mailman/listinfo/python-list
