PLEAC-Python - 0 views

  •  
    Following the Perl Cookbook (by Tom Christiansen and Nathan Torkington, published by O'Reilly) spirit, the PLEAC Project aims to gather fans of programming, in order to implement the solutions in other programming languages. In this document, you'll find an implementation of the Solutions of the Perl Cookbook in the Python language.

rsync implemented in Python - 0 views

  • This script mimics rsync which is available for the unix platform and have been ported to win32 one. It is a sort of advanced version of xcopy. Its aim is to selectively synchronize folders. More precisely it copy selective parts of a folder to a destination folder and in addition can remove parts of the destination folder that do not correspond to parts of the original folder. I like its capability to avoid copying files through the .cvsignore mechanism or the pattern matching mechanism and its capability to delete files that are no longer relevant, not to mention that because it's a python script anyone can easily fix or improve it as he whish.

Eli Bendersky's website » Python metaclasses by example - 12 views

    • Mauro De Giorgi
       
      Start read from here
  • Study and understand this example and you’ll grasp most of what one needs to know about writing metaclasses.
  • To control the creation and initialization of the class in the metaclass, you can implement the metaclass’s __new__ method and/or __init__ constructor [6]. Most real-life metaclasses will probably override just one of them. __new__ should be implemented when you want to control the creation of a new object (class in our case), and __init__ should be implemented when you want to control the initialization of the new object after it has been created.
  • ...3 more annotations...
  • It’s important to note here that these print-outs are actually done at class creation time, i.e. when the module containing the class is being imported for the first time. Keep this detail in mind for later.
  • So when the call to MyMeta is done above, what happens under the hood is this:

Ubiquity's Python Feed Plugin at Toolness - 0 views

  •  
    A few weeks ago I wrote about Ubiquity Feed Plugins, which are basically just a way of separating the user interface of subscribing to a new feature from the implementation of the feature itself. As I've written about before, one of the things I've missed about the Mozilla development environment is its support for the Python programming language. Aside from being humane and having a great community, it has functionality that could complement the Mozilla platform quite nicely. So we've whipped up a quick proof-of-concept Python Feed Plugin for Ubiquity to explore this possibility.

Types of ERP Systems - 0 views

  •  
    Thinking of ways to improve your business's efficiency isn't always difficult, but implementing these ideas can be. Daily operations are challenging enough, and adding a new way of solving problems on top of it can be intimidating. Making informed decisions requires getting to know your options. We've prepared a guide to various types of ERP systems and what they do.

mpmath - Google Code - 0 views

  • Mpmath is a pure-Python library for multiprecision floating-point arithmetic. It provides an extensive set of transcendental functions, unlimited exponent sizes, complex numbers, interval arithmetic, numerical integration and differentiation, root-finding, linear algebra, and much more. Almost any calculation can be performed just as well at 10-digit or 1000-digit precision, and in many cases mpmath implements asymptotically fast algorithms that scale well for extremely high precision work. If available, mpmath will (optionally) use gmpy to speed up high precision operations.

dbtxt (page 43) python database module - 0 views

  • I wrote dbtxt because I needed a small, flat database in a python environment that didn't depend upon any external libraries. Most libraries are contaminated with the GPL, and this needed to be OK for commercial distribution without any complications. So that's what we have here - a complete (though small) database system that depends on nothing at all other than the Python language and its internal libraries. The entire database comes in at about 20k bytes (that's right, "k", not hundreds of k or megabytes) and I was able to implement all the functions I needed. So I was happy. Will you be happy? Well, download it and read the docs and see what you think. The download, zipped, is about 13k. Yep. 13k. :-) By all means, if you have a need for the same kind of thing, feel free to make any use of dbtxt you please. I have released it as PD, so you can use it in projects that are commercial, GPL, BSD, PD, private, government... whatever you like. Below you'll find a basic description taken from beginning of the docs; in the archive you'll download there is complete documentation, two sample databases, a test program and the database engine itself.

Charming Python: Inside Python's implementations - 0 views

  • To attempt to explain it in the simplest terms, a continuation is a representation, at a particular point in a program, of everything the program is capable of doing subsequently. A continuation is a potential that depends on initial conditions. Rather than loop in a traditional way, it is possible to invoke the same continuation recursively with different initial conditions. One broad claim I have read is that continuations, in a theoretical sense, are more fundamental and underlie every other control structure. Don't worry if these ideas cause your brain to melt; that is a normal reaction.

ONLamp.com -- Introduction to Stackless Python - 0 views

  • Stackless Python is an alternative implementation of Python created by independent developer Christian Tismer. He started with the conventional Python language processor managed by the language's inventor, Guido van Rossum, and patched his own Stackless invention in place of a small but central part of Python's internals. Stackless Python is the result. This article introduces Tismer's technology and its significance. In future articles, you'll be able to read about how to make your own start at programming Stackless Python, as well as the prospects for a merger between Stackless and the main Python distribution.

NumericAndScientific - PythonInfo Wiki - 0 views

  • PyACTS- http://www.pyacts.org -- PyACTS is a collection of Python Modules that are very useful to Parallel Computing in a High Performance Computing environment. This packages incorporates several modules like PyBLACS (allows communication data for Linear Algebra), PyPBLAS (distributed Matrix Operations) and PyScaLAPACK (solve linear systems and get the eigenvalue problems). These libraries are part of PyACTS project that provide interfaces to the ACTS Collection. Also is provided a parrallel interpreter for using this package that implements message-based parallel programming using MPI.

blog.bjrn.se: TrueCrypt explained - 0 views

  • he most popular cryptographic software for Windows is probably TrueCrypt. In this article I will explain how TrueCrypt works and as a by-product a working Python implementation will be provided. This article is written from a programmer perspective and the math will be kept to the minimum. The emphasis is on how TrueCrypt uses cryptographic primitives such as AES and SHA-1, not how the primitives themselves work.

ONLamp.com -- Introduction to Stackless Python - 0 views

  • What's the relation between these benefits and Stackless's implementation details? Here's a quick sketch: Continuations are the general-purpose concurrency construct. A continuation represents all the future computations of a particular program. Capturing all this control flow in a single conceptual object makes it programmable: It becomes possible to calculate or reason over the control flow. In particular, there's great scope for optimizing assignment of different calculations to different processes or threads or even hosts.

Python Patterns - Implementing Graphs - 0 views

  • Few programming languages provide direct support for graphs as a data type, and Python is no exception. However, graphs are easily built out of lists and dictionaries. For instance, here's a simple graph (I can't use drawings in these columns, so I write down the graph's arcs):
