I'm not sure this is possible, but I would like to have a list of objects A=[a,b,c,d,...,z]
where, in the midst of a lot of processing I might do something like, A[0].do_something_which_changes_the_properties() which alter the properties of the object 'a'. The trick is that I would like A to be mysteriously aware that something about the object 'a' has changed so that when I revisit A, I will know that the other items in the list need to be refreshed to reflect the changes in A as a result of changing 'a'. Even better would be to automatically percolate the subsequent changes that resulted from altering 'a' for the rest of the items in the list. Naturally, all of these items are related in some parent-child fashion. that might be a lot to ask, however. Any advice appreciated. -- http://mail.python.org/mailman/listinfo/python-list
