-\begin{opcodedesc}{PRINT_ITEM_TO}{}
-Like \code{PRINT_ITEM}, but prints the item second from TOS to the
-file-like object at TOS. This is used by the extended print statement.
-\end{opcodedesc}
-
-\begin{opcodedesc}{PRINT_NEWLINE}{}
-Prints a new line on \code{sys.stdout}. This is generated as the
-last operation of a \keyword{print} statement, unless the statement
-ends with a comma.
-\end{opcodedesc}
-
-\begin{opcodedesc}{PRINT_NEWLINE_TO}{}
-Like \code{PRINT_NEWLINE}, but prints the new line on the file-like

\begin{opcodedesc}{BREAK_LOOP}{}
Terminates a loop due to a \keyword{break} statement.

-\keyword{print} evaluates each expression in turn and writes the
-resulting object to standard output (see below). If an object is not
-a string, it is first converted to a string using the rules for string
-conversions. The (resulting or original) string is then written. A
-space is written before each object is (converted and) written, unless
-the output system believes it is positioned at the beginning of a
-line. This is the case (1) when no characters have yet been written
-to standard output, (2) when the last character written to standard
-output is \character{\e n}, or (3) when the last write operation on
-standard output was not a \keyword{print} statement. (In some cases
-it may be functional to write an empty string to standard output for
-this reason.) \note{Objects which act like file objects but which are
-not the built-in file objects often do not properly emulate this
-aspect of the file object's behavior, so it is best not to rely on
-this.}
-\index{output}
-\indexii{writing}{values}
-
-A \character{\e n} character is written at the end, unless the
-\keyword{print} statement ends with a comma. This is the only action
-if the statement contains just the keyword \keyword{print}.

-\indexii{newline}{suppression}
-
-Standard output is defined as the file object named \code{stdout}
-in the built-in module \module{sys}. If no such object exists, or if
-it does not have a \method{write()} method, a \exception{RuntimeError}
-exception is raised.

-
-\keyword{print} also has an extended\index{extended print statement}
-form, defined by the second portion of the syntax described above.
-This form is sometimes referred to as ``\keyword{print} chevron.''
-In this form, the first expression after the \code{>>} must
-evaluate to a ``file-like'' object, specifically an object that has a
-\method{write()} method as described above. With this extended form,
-the subsequent expressions are printed to this file object. If the
-first expression evaluates to \code{None}, then \code{sys.stdout} is
-used as the file for output.
