The Python byte compiler can be invoked on an AST object to produce
-code objects which can be used as part of an \keyword{exec} statement or
-a call to the built-in \function{eval()}\bifuncindex{eval} function.
+code objects which can be used as part of a call to the built-in
+\function{exec()}\bifuncindex{exec} or \function{eval()}
+\bifuncindex{eval} functions.
This function provides the interface to the compiler, passing the
internal parse tree from \var{ast} to the parser, using the
source file name specified by the \var{filename} parameter.
