\subsection{Object Presentation}
-In Python, there are three ways to generate a textual representation
-of an object: the \function{repr()}\bifuncindex{repr} function (or
-equivalent back-tick syntax), the \function{str()}\bifuncindex{str}
-function, and the \keyword{print} statement. For most objects, the
-\keyword{print} statement is equivalent to the \function{str()}
-function, but it is possible to special-case printing to a
-\ctype{FILE*} if necessary; this should only be done if efficiency is
-identified as a problem and profiling suggests that creating a
-temporary string object to be written to a file is too expensive.
