+\subsubsection{Code Objects.}
+\obindex{code}
+
+Code objects are used by the implementation to represent
+``pseudo-compiled'' executable Python code such as a function body.
+They differ from function objects because they don't contain a
+reference to their global execution environment.  Code objects are
+returned by the built-in \code{compile()} function and can be
+extracted from function objects through their \code{func_code}
+attribute.

+A code object can be executed or evaluated by passing it (instead of a
+source string) to the \code{exec} statement or the built-in
+\code{eval()} function.
