+##############################
+  Python built-ins reference
+##############################
+
+Python comes with a number of built-in functions and classes.
+
+The built-in classes include data types that would normally be considered part
+of the "core" of a language, such as numbers and lists.  For these types, the
+Python language core defines the form of literals and places some constraints
+on their semantics, but does not fully define the semantics.
+
+The built-ins also include functions and exceptions --- objects that can
+be used by all Python code without the need of an :keyword:`import` statement.
+Some of these are defined by the core language, but many are not essential for
+the core semantics and are only described here.
+
+.. seealso::
+
+   In addition to the built-ins, Python provides an extensive importable
+   standard library, see :ref:`library-index`.
+
+.. We don't use :numbered: option for the TOC below as it enforces
+   numbered sections for the entire builtin docs.  If desired,
+   :numbered: can be enabled on a per-page basis.
