If that is what you mean then I interpret your statement >AP> `with an assignment the search for the lefthand variable >AP> depends on whether the lefthand side is a simple variable or >AP> more complicated' as meaning that the search for `a' in `a.b = c' would be different than the search for `a' in `a = b'. Well, it is not. But I can understand the confusion. Namely, `a = b' introduces a binding for `a' in the local scope, unless `a' was declared global. So the search will find `a' in the local scope and it stops there. On the other hand `a.b = c' will not introduce a binding for `a'. So the search for `a' may stop in the local space (if there was another binding for `a' in the local scope) or it may need to continue to outer scopes. The difference, however is not the complicatedness of the lefthand side but whether the local scope contains a binding for the variable. -- Piet van Oostrum <[EMAIL PROTECTED]> URL: http://www.cs.uu.nl/~piet [PGP 8DAE142BE17999C4] Private email: [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
