Another way of solving your *actual* problem. "Replace all references to object1 with object2 instead" is a means to an end, not the end itself. What are you trying to solve? Focus on *that* problem, not your supposed solution, because "replace all..." is doomed to fail. There is no "master list" of objects available to you. All you have is one or more namespaces containing objects. Many of those objects themselves will contain other objects, and so on. All you can do is walk through each namespace in turn, recursively into each object, searching for the object you want to replace. But that may not help you, because there's no guarantee that having found it you can replace it safely, *or at all*. While Python does allow code to reach deeply into the internals of a wide range of objects -- very little is truly private in Python -- do you *really* want to be taking responsibility for safely replacing objects from within arbitrary other objects? If so, Python gives you the tools to shoot yourself in the foot, although it won't necessarily be easy, or pretty, or fast. So, tell us what your real problem is, the end towards which you think "replace all..." is the solution, and we'll see if we can help. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
