  • Python Getopt SIG

    Python Getopt SIG Python Getopt SIG The purpose of this SIG was to come up with a new and improved library for command-line parsing in Python 2.3. Everybody seems to agree that the venerable getopt module just doesn't do enough. The trick is to find something that is sufficiently powerful and flexible without being too complex to use, especially for novice programmers. The SIG was kicked off shortly after David Goodger and Greg Ward (your humble narrator and champion of this SI...

Decisions made Everyone seemed to agree with my p...

Greg Ward's "distutils" package is included: this will make installing, building and distributing third party packages much simpler. There's now special syntax that you can use instead of the apply() function. f(*args, **kwds) is equivalent to apply(f, args, kwds). You can also use variations f(a1, a2, *args, **kwds) and you can leave one or the other out: f(*args), f(**kwds). The built-ins int() and long() take an o...

  • SIG for Ultra Large-Scale Systems

    SIG for Ultra Large-Scale Systems This special interest group (SIG) exists in order to discuss the emerging field of computing in the context of ultra large-scale systems and how such systems relate to or can be built with Python. The term "Ultra Large-Scale Systems" comes out of the research that was done in 2005-2006 by the Carnegie Mellon Software Engineering Institute's ULS Systems team. It entails the "creation" of systems of the next 10-20 years (and possibly beyond),...

In 1.6 and earlier, they never produced a sign, and raised an error if the value of the long was too large to fit in a Python int. In 2.0, they produced a sign if and only if too large to fit in an int. This was inconsistent acr...

    Python Patterns - An Optimization Anecdote Warning This page stays here for historical reasons and it may contain outdated or incorrect information. The other day, a friend asked me a seemingly simple question: what's the best way to convert a list of integers into a string, presuming that the integers are ASCII values. For instance, the list [97, 98, 99] should be converted to the string 'abc'. Let's assume we want to write a function to do this. The first version I came ...
