Short answer: no.

Long answer: All-uppercase identifiers are considered constant, i. e.  "don't
change me", just as names with one or two leading underscores are considered
"private".

For class instances, there are properties (in Python 2.2 and later, earlier you
have to override __getattr__ and __setattr__), that can be used to create
read-only attributes.
