\subsection{Interactive Interpreter Changes}
|
||||
|
||||
In the interactive interpreter, \code{quit} and \code{exit}
|
||||
have long been strings so that new users get a somewhat helpful message
|
||||
when they try to quit:
|
||||
|
||||
\begin{verbatim}
|
||||
>>> quit
|
||||
'Use Ctrl-D (i.e. EOF) to exit.'
|
||||
\end{verbatim}
|
||||
|
||||
In Python 2.5, \code{quit} and \code{exit} are now objects that still
|
||||
produce string representations of themselves, but are also callable.
|
||||
Newbies who try \code{quit()} or \code{exit()} will now exit the
|
||||
interpreter as they expect. (Implemented by Georg Brandl.)

% datetime.datetime() now has a strptime class method which can be used to

% create datetime object using a string and format.

\item In the \module{gc} module, the new \function{get_count()} function
|
||||
returns a 3-tuple containing the current collection counts for the
|
||||
three GC generations. This is accounting information for the garbage
|
||||
collector; when these counts reach a specified threshold, a garbage
|
||||
collection sweep will be made. The existing \function{gc.collect()}
|
||||
function now takes an optional \var{generation} argument of 0, 1, or 2
|
||||
to specify which generation to collect.
|
||||
|
||||
\item A new \module{hashlib} module has been added to replace the
|
||||
\module{md5} and \module{sha} modules. \module{hashlib} adds support
|
||||
for additional secure hashes (SHA-224, SHA-256, SHA-384, and SHA-512).
