In Python, there are three ways to generate a textual representation In Python, there are two ways to generate a textual representation
of an object: the \function{repr()}\bifuncindex{repr} function (or of an object: the \function{repr()}\bifuncindex{repr} function, and
equivalent back-tick syntax), the \function{str()}\bifuncindex{str} the \function{str()}\bifuncindex{str} function. (The
function, and the \keyword{print} statement. For most objects, the \keyword{print} function just calls \function{str()}.)
\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.
These handlers are all optional, and most types at most need to These handlers are both optional.
