• Parade of the PEPs

  ...literals because that would break existing code. Maybe "from __future__ import interpolation" would enable interpolation in string literals? (Only in literals!) There's also the question whether to allow arbitrary expressions like print "The area is ${x*y}" PEP 216 - Docstring Format - Zadka This has very little contents. Maybe it should be withdrawn? There are several other PEPs that deal with doc strings, notably 256-258, which I like much better. PEP 228 - R...

  ...values. A 'continue' statement can now appear in a try block within the body of a loop. It is still not possible to use continue in a finally clause. Standard library mailbox.py now has a new class, PortableUnixMailbox which is identical to UnixMailbox but uses a more portable scheme for determining From_ separators. Also, the constructors for all the classes in this module have a new optional 'factory' argument, which is a callable used when new message classes must be instantiated by the...

  ...values in a dataset. itertools has a new function groupby() that acts a little like an SQL "GROUP BY" statement. It also gained a function tee() that returns N independent iterators that replicate the iterator passed as an argument. A new function basicConfig() was added to the logging package to simplify setup for logging. There is also a new TimedRotatingLogFileHandler which automatically rotates log files at a fixed interval. The operator module gained functions attrgetter() and ite...

  ...literal shape. There may be instances where we can approve a secondary reflection, for example as-if the logo is also in a mirror or a pond within an overall image; but even there, the primary focus must be on the literal logo. For illustration: Logo Discussion Using the original logo without any additional elements is fine (including, as here, without the optional shadow). Rotation of the logo is permitted; if the rotation is used to create a derived version by adjacency to other el...

  ...literals. Internals Fixed several buffer overflow vulnerabilities in calculate_path(), which is called when the interpreter starts up to determine where the standard library is installed. These vulnerabilities affect all previous versions of Python and can be exploited by setting very long values for PYTHONHOME or argv[0]. The risk is greatest for a setuid Python script, although use of the wrapper in Misc/setuid-prog.c will eliminate the vulnerability. Fixed...

  ...values displayed in the GUI's grid. The order in which the statements are executed depends upon the dependencies between them. For example, if cell A1 references the value of B1, then B1 must be evaluated first. This provides us with the basic spreadsheet model that has proven so valuable for ad-hoc investigation of numerical models. Figure 2. The basic steps Resolver One uses to evaluate cell formulae.

Introduction My first look at Python was an accident, and I didn't much like what I saw at the time. It was early 1997, and Mark Lutz's book Programming Python from O'Reilly & Associates had recently come out. O'Reilly books occasionally land on my doorstep, selected from among the new releases by some mysterious benefactor inside the organization u...
