Sexy Lexing with Python | Evan Fosmark

stargaming — Thu, 26 Feb 2009 12:33:00 -0500

In the re module there is a class called Scanner that can do lexical sanning. It is completely undocumented other than for a small example code block found on the Python-Dev mailing list, but well worth mentioning. Tagged by stargaming under python, idiom, parsing,

Factor

stargaming — Sun, 22 Feb 2009 08:55:00 -0500

Factor is an expressive, fast and full-featured Concatenative language. Concatenative and stack-based languages have not received much attention from the programming community ever since Forth began a slow decline in the 80's. Once you learn some common idioms, many problems can be more cleanly expressed in a concatenative language compared to an applicative language. Tagged by stargaming under programming, languages,

To assert or assertEqual in Python unit testing - Peterbe.com (Peter Bengtsson on Python, Zope, Kung Fu, London and photos)

Perhaps some much more clever people than me can explain what a cardinal sin it is to not use the unittest methods over the lazy more pythonic ones. Tagged by stargaming under python, testing, idiom,

James Tauber : Two Fun(ctional) Questions

We're doing function composition but that's not what x is doing. It's not currying, it's not thunking, it's not trampolining. Is there a word for it? Tagged by stargaming under python, idiom,

Version-specific import « ActiveState Code

stargaming — Thu, 18 Sep 2008 10:52:00 -0400

This recipe presents a method for letting client code specify on one line which version of "tools" they wish to use -- and then import from the tools package as normal. Behind the scenes, the recipe is making sure that the client works with the version of the package that they requested. If the client ever wants to change versions, it's a one-line change at the top of their code. Tagged by stargaming under python, idiom,

Chris's Wiki :: blog/python/ImportableMain

stargaming — Sun, 07 Sep 2008 08:42:00 -0400

When I first started coding in Python, I didn't know what I was doing. So I structured my Python programs the way I would write Bourne shell scripts or Perl programs, writing functions as necessary and useful but otherwise putting all of the logic and code in the program's file outside of functions (in what I now call 'module scope').

Django on Jython, Python Implementations and Performance

stargaming — Wed, 27 Aug 2008 07:35:00 -0400

Django now runs on Jython which is great news. Jeff Hardy is also making progress running Django on IronPython. As usual the news sparked a plague of comments on Reddit. There seems to be a lot of confusion about the different implementation of Python, and which bits of CPython acts as the reference implementation. Tagged by stargaming under django, python, idiom,

"Design Patterns" Aren't

stargaming — Sat, 23 Aug 2008 05:02:00 -0400

The "design patterns" movement in software claims to have been inspired by the works of architect Christopher Alexander. But an examination of Alexander's books reveals that he was actually talking about something much more interesting. Tagged by stargaming under programming, idiom,

randomwalker's journal - Pypes work! (more or less)

stargaming — Tue, 19 Aug 2008 10:38:00 -0400

My bitching about function call syntax motivated someone to actually try to solve the problem in Python using operator overloading. It was a great first step, but I tried to make it useful enough to write code using pipe syntax. Tagged by stargaming under python, idiom,

An Introduction to Thread Programming

stargaming — Tue, 12 Aug 2008 05:32:00 -0400

This writing explains the basics of thread programming, for a beginner, the concept of thread programming is often intimidating with the complexities involved in it, therefore its very important to get the basics right. This article explains the basics of threads, creating multiple threads of control from the main program using a simplified syntax and also some slightly advanced concepts like acquiring and releasing locks.

JJinuxLand: Python: intern()

stargaming — Sun, 03 Aug 2008 11:15:00 -0400

I'm working with a lot of data, and running out of memory is a problem. When I read a line of data, I've often seen the same data before. Rather than have two pointers that point to two separate copies of "foo", I'd prefer to have two pointers that point to the same copy of "foo". Tagged by stargaming under python, idiom,

the occasional occurrence » Blog Archive » Customizing the Python Import System

I got to thinking about what other ways I could hack the import system, and came up with a little web importer. I’ll post the code below, only because I think it is a clever trick, not that it is something to use in development of a Real Application. Tagged by stargaming under python, idiom,

Tip: Use string literals instead of the pass statement? : David Stanek’s Digressions

stargaming — Sun, 03 Aug 2008 01:54:00 -0400

The pass statement is simply used where the Python syntax requires a statement, but the application doesn’t need any logic. Typically it is accompanied by a comment explaining why it is there. Tagged by stargaming under python, idiom,

Python best practices

stargaming — Sun, 13 Jul 2008 01:53:00 -0400

Sometimes even good programmers at their first tries of Python use less than optimal solutions and language constructs. In the years Python has accumulated few redundancies and few warts, but it's a generally clean language still, so with a page like this you can avoid the most common ones. This page hopes to be really simple and short enough, you can find explanations online elsewhere. Tagged by stargaming under python, idiom,

stargaming — Tue, 20 May 2008 09:48:00 -0400

If you haven t had much to do with ActionScript or Visual Basic, right now you might be thinking huh? Basically the with statement in both of these languages allows one to access the attributes of an object as if they were in the local scope. I know, I know. Why would you want to do this? I have no idea, but I thought it was cool that it was even possible in Python : Tagged by stargaming under python, idiom,

Patrick Roberts's Blog

stargaming — Fri, 11 Apr 2008 11:22:00 -0400

It's often convenient to imagine a process as a tree-shaped (or graph-shaped) assembly line. Inputs flow in through the leaves and are transformed, filtered or reduced where branches join. This well represents lazy-functional programming. Say one wants the words from a line-delimited file, excluding acronyms, then converted to lower case and stored in a set for quick lookup.
