Python is based on objects, but it is not an object-oriented language. It is a multi-paradigm language: it includes elements of OOP, functional, procedural and imperative programming. Some of these are fundamental to Python: the "import" statement is pure imperative style. For example, Python has: import module # imperative style len(mylist) # procedural map(func, sequence) # functional mylist.sort() # object-oriented With a third-party package, Pyke, you can use Prolog-style logic programming: http://pyke.sourceforge.net/ (albeit with a procedural syntax). There are probably third-party packages for agent-based programming as well. If you don't like OOP, you can write your code using a functional style, or a procedural style. List comprehensions and generator expressions are *very* common in Python, which come from functional and pipeline styles of programming. If you really, really hate OOP, you can even write your own wrappers for Python objects. Unlike Java, Python encourages by example the use of shallow class hierarchies. Most Python classes are only two levels deep: object +-- list +-- tuple +-- dict +-- set etc. instead of the deep, complex hierarchies beloved by some OOP languages: Object +-- Collection +-- Sequence | +-- MutableSequence | | +-- IndexableMutableSequence | | +-- SortableIndexableMutableSequence | | +-- SortableIndexableMutableSequenceArray | | +-- List | +-- ImmutableSequence | +-- IndexableImmutableSequence | +-- SortableIndexableImmutableSequence | +-- SortableIndexableImmutableSequenceArray | +-- Tuple +-- Mapping etc. So while everything in Python is an objects, the language itself is only partly object oriented, and it rarely gets in the way. The OO aspect of Python is mostly syntax and namespaces. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
