ANN: Porcupine Web Application Server 0.0.8 released
The brand new version of Porcupine introduces quite a few new cool features and many improvements that ease and accelerate the development process. Our main goal was to remove any constraints that expect the files of a Porcupine application to reside inside more than one folder tree. As a result, it is now attainable to develop your application working inside a single folder tree only. The application object was greatly simplified. The application's UI XML definition along with its script are now external files instead of having them embedded inside the object. This way, you can easily edit these files using your favourite editor. Additionally, the Porcupine desktop includes a new utility called HyperSearch. Use this utility to search the entire Porcupine database for objects that meet specific criteria such as text parts contained in their title or description and their modification date. The QuiX engine includes a completely rewritten event subsystem, in order to achieve a unified way of attaching and detaching DOM and custom event handlers. Furthermore, QuiX is now compatible with Internet Explorer 7 including many performance enhancements. Two new widgets are also added to the list of available widgets. An IFrame widget that enables the display of external sites inside the Porcupine desktop, and a group box. Enjoy.

No fair: you only just added atomsmasses! ;-)
However, it seems to me that your atomsmasses dictionary is going to be
entirely predictable, and you are still focusing on storing the *names*
of things rather than building up a usable data structure. Indeed I
suspect that your problem can be solved using only the names of the
elements, and not the names of the variables that hold various
attributes of the elements.
Perhaps if you explain in plain English what you *really* want to do we
can help you find a more Pythonic solution. It'll probably end up
something like this:
mass = {}
for element in ['C', 'O', ..., 'Zn']
mass[element] = monoVarcalc(element)
But I could, of course, be completely wrong ... it wouldn't be the first
time. Do you understand what I'm saying?

Here I'm lost. What's the advantage of this? It looks more convoluted. And speaking of convoluted, what about efficiency? There is much talk of efficiency on this forum. I (crudely) benchmark your previous example approximately three times slower than a simple inner function taking and returning three parameters.

It was a good choice, because I decided to improve the timer - learning some more Python along the way! So, the idea is: - cron runs the script at a specific time - the script starts mplayer, and will keep checking the clock until it's time to kill mplayer - after mplayer has exited, oggenc is started to turn the raw WAV into ogg - and finally the remaining WAV is deleted This basic setting is quite easy, and I used os.spawnvp(os.P_WAIT,...), along with another CRON entry to kill mplayer. But then I got more ambitious: I wanted the script to keep checking if mplayer was alive - in case the connection goes down. Moreover, I would rather have the script stop mplayer than cron. At this point, I thought I should get some professional help... :) What is the right way to go? Would threads be overkill? If so, where can I go about looking for process control/management without delving into complex daemon architectures? So, rather than asking for code, I'm looking for guidance - this is a didactic experience! Cheers, Renato I would suggest you take a look at Python 'commands' module.

OK...
from the start.
im trying to develop a simple command line application for determining
the degree of substitution (DS) on a polymer backbone from elemental
analysis, i.e., the % weights of different elements in the
monomer-substituent compound ( i want each element to give a result and
heaviest atoms give the most accurate results).
most basic comp chem programs use input files but i dont know anything
about file iteration yet and want the program to be as user friendly as
possible..i.e. command line prompt. GUI would be great but too much for
me at this stage
at the start of the script i have 2 dictionaries 1) containing every
atom in the periodic table with associated isotopic average masses 2)
containing the molecular forumla of the monomer unit...eg for cellulose
AGU {'C': 6, 'H': 10, 'O': 5}.
the basic steps are
1. calculate the weight percentage values for each atom in the monomer
2. iterate into dictionaries from DS=0 - DS=15 (0.5 step) the
projected % values for the monomer plus substituent, for EACH atom in
the compound.
3. find the (local) minimum from each dictionary/atom to give the
appropriate DS value.
*Note* I have to iterate ALL the values as there is a non-linear
relationship between % values and DS due to the different atomic weights
The computer seems to cope with this in about 10 seconds with the above
parameters and about 8 elements for the iteration step
I have a script which works perfectly from some time ago but the problem
is, some of the samples contain excess water so i was going to use the
heaviest atom to give the most accurate DS value i could and then adjust
the polymer back bone dictionary to include the initial substituent from
step 3. Then do the calculation again for water {'H': 2, 'O': 1} as the
new substituent. Once i determine the new 'DS' value of water its simple
to recalculate the % values...iterate..find (local) minima and get more
accurate DS values for all the heavy atoms (not including Hydrogen or
Oxygen).
...
I would like to get the script running now to get some results from our
experimental data which shoudnt take too long but eventually i dont want
to rely on the monomer dictionary...just input the elements and number
of atoms of each element in the starting

Instead, Python tries calling obj[index] starting at 0 and keeps going until an IndexError exception is raised, then it halts the for loop. So, think of it like this: pretend that Python expands the following code: for x in obj: block into something like this: index = 0 while True: # loop forever try: x = obj[index] block # can use x in block except IndexError: # catch the exception and escape the while loop break index = index + 1 # and now we're done, continue the rest of the program That's not exactly what Python does, of course, it is much more efficient, but that's a good picture of what happens. - where the while 1:-loop is quitted.

I am not too familiar with this way of using objects. Actually it isn't all that different from a list, because a list is also an object. But this way it's attribute names instead of list indexes which is certainly easier to work with. Very good! In short I think an outer keyword (or whatever it gets called) will just add another way of doing something I can already do, and potentially makes further refactoring harder. Here I'm lost. What's the advantage of this? It looks more convoluted. I'll agree that having to explicitly define a namespace class first does add some convolution. But if you refer to having to prefix you outer variables with scope. then this would be the same as claiming that the explict use of self is convoluted, which is a valid opinion, so fair enough, but I can't say that I agree. It should also be noted that although I have to declare and create a scope object. My method doesn't require the attributes passed back from the inner function be pre-declared, should I during coding realise that I need to return another attribute I just assign it in the inner function and use it in the outer function. I would count that as less convoluted, YMMV. And speaking of convoluted, what about efficiency? There is much talk of efficiency on this forum. I (crudely) benchmark your previous example approximately three times slower than a simple inner function taking and returning three parameters. It was actually the aspect of increased efficiency that prompted me to play with the idea of allowing direct outer writes. Did you have optimisation turned on ? As I see it there should be no reason an optimiser couldn't transform my code into the same code we might expect from your outer keyword example, as the scope object's type and attributes are all contained within (thus known to) the outer function defenition. Wether CPython's optimiser does this or not, I don't know. Thats -2 import-this points already. Which ones are the two? Explicit is better than implicit.

Python tools for managing static websites?
Are there Python tools to help webmasters manage static websites? I'm talking about regenerating an entire static website - all the HTML files in their appropriate directories and sub-directories. Each page has some fixed parts (navigation menu, header, footer) and some changing parts (body content, though in specific cases the normally fixed parts might change as well). The tool should help to keep site editing DRY every piece of data, including the recurring parts, should exist only once. The above should be doable with any decent templating tool, such as those forming part of most CMSes and full-stack web-frameworks. Normally I might have just resorted to a CMS/web-framework, running locally on the webmaster's station, with the only addition being a mechanism for generating all pages composing the site and saving them as files. But such a solution might not be enough, as the system I'm looking for must be able to control the physical traits of the website as a collection of files - e.g., creation and distribution of files among several physical directories and subdirectories. Any advice would be appreciated, -Chris -- http://mail.python.org/mailman/listinfo/python-list

I am stuck between using a threaded server, and using an event driven server. I've been told time and time again that I should use an event driven server design (that is, use twisted). I didn't hear the specifics of how you got that advice, so I can't comment specifically. I will say that I've have heard a lot of advice against threads that struck me as simply naive. Much of it is quite well informed. There is a lot of interaction between the clients and they would often need to write to the same list of values, which of course becomes a problem with a threaded server - so event driven solves that problem, and I assumed it would solve all my problems. [...] The purely event-driven style solves some problems, but creates others. You're forced to structure your code around the blocking behavior, and that's not the structure anyone would choose for clarity or maintainability. This is not the case. However, much event-driven code is written this way anyway, intentionally, for clarity. If you _want_ opaque code, or for some reason think it is not opaque to write code in this manner, then there you can use a library which supports this. Suppose we're enhancing an event-driven system, and decide to relocate some datum from a variable to the database. Suppose in one or more places, accessing the data happens in a call chain several function down from the event loop. We can't just change the function that accesses the data because a synchronous database call could block and stop event processing. Every interface on the call chain is broken. As it must be, because you have changed the atomicity of an operation. Transparently propagating this up a call stack leads to bugs which are similar to those found in a system based on pre-emptive multithreading. [...] I will want the server to support as many users as is possible on any given machine - and so wasted CPU cycles is something I am trying to avoid. Python is a great scripting language, but squeezing out machine performance is not where scripting languages shine. That said, you might start in Python, to see if your system is successful and the performance of your server really is a limiting factor. Is the only solution to use a threaded server to let my clients make their requests and receive a response in the fastest possible time? Maybe. Probably not. It's all good -- multi-threading is your friend. Multithreading is _someone's_ friend. Probably not the OP's, whose original post made it sound very strongly like he just needed network concurrency, which is a perfectly fine use-case for event-driven style rather than pre-emptive threading.

Thus, on one hand, I am hesitant to use execfile(), since I *do* want to wrap the plugin up, but on the other hand, I want the plugin to be able to use functions from the original script. Any ideas? I have a system that uses modules as plugins also. These are loaded dynamically when the user specifies them from a gui. I put all these modules in an array using the __import__ function. I found, though, that I needed to specify whether or not each module had actually loaded, or if there had been an exception (module not found or whatever). So I wrote a wrapper object that would try to load the module and store it as a local attribute. I made my wrapper object implement functions like __getattr__ and pass any unknown calls into the module object itself, making the wrapper object act as if it was the module, but having extra capabilities, such as being able to tell me if the module had actually loaded or not.

then we'd be on a wild goose chase. This could be because your python
installation is goofy, or because you copied in your code incorrectly.
Shit happens, and I'd rather not even start down one of those blind
alleys. Third, it provides a useful frame for how to look at your
code. While a traceback might look like a big mess at first, it's
actually pretty easy to skim through once you get used to it, and it
tells me where to focus my attention in your code.

Thanks, that's very helpful. Playing with your code a bit, I narrowed
the problem down to the array.array() structure. Looking at
help(array), there's a method defined called __deepcopy__, which, it
seems, takes no arguments, while deepcopy is passing it one argument.
Looks like a bug in the array module to me. Maybe others with more
experience using array will have some deeper insight.
I don't understand why python would insist that everything must be a
refrence...
It is of course helpful sometime but other times its not... and now
I'm sorta out
of luck...
I don't know how to make this structure immutable... Pickle it? Seems
very
inefficient to me...
Every time I pass a variable now I will worry that it will be changed
by the function...
I haven't worried about things like this since the very early days of
BASIC
I don't know.. maybe I have more to learn.

You can't do that.) It might also be feasible to do something like this with a decorator...? Every time I pass a variable now I will worry that it will be changed by the function... I haven't worried about things like this since the very early days of BASIC I don't know.. maybe I have more to learn. Well, there are at least solutions to this paranoia that occur to me: -make a deep-copy of the object in question before calling the function, and then pass the copy to the function so that it can't alter the original -trust/read the functions' documentation. Most functions that alter the contents of their parameters are kind enough to note as much. If functions go bunging with your parameters without documenting it, the function's coder needs to be smacked. -tkc -- http://mail.python.org/mailman/listinfo/python-list
Re: enumerate improvement proposal
James Stroud wrote:
I think that it would be handy for enumerate to behave as such:
def enumerate(itrbl, start=0, step=1):
i = start
for it in itrbl:
yield (i, it)
i += step
I proposed something like this long ago and Guido has already rejected
it. Part of the reason is that it doesn't match his mental model of
enumerate being about pairing sequence elements with their indices.
Another reason is that the syntax has more than one obvious
interpretation:
enumerate('abcdef', 2) -- (2, 'c'), (3, 'd'), ...
enumerate('abcdef', 2) -- (0, 'c'), (1, 'd'), ...
enumerate('abcdef', 2) -- (2, 'a'), (2, 'b'), ...
Also, the order of arguments is odd in comparison with the output order
-- this suggests a syntax like enumerate(2, 'abcdef') -- (2, 'a'), (3,
'b') ...
FWIW, it is not hard to roll-your-own with something like:
for pagenum, page in izip(count(1), book): ...
The izip/count combination runs at C speed, matches enumerate() in its
efficiency, and is arguably clearer in expressing its intended
behavior.

I am not too familiar with this way of using objects. Actually it isn't all that different from a list, because a list is also an object. But this way it's attribute names instead of list indexes which is certainly easier to work with. Very good! In short I think an outer keyword (or whatever it gets called) will just add another way of doing something I can already do, and potentially makes further refactoring harder. Here I'm lost. What's the advantage of this? It looks more convoluted. I'll agree that having to explicitly define a namespace class first does add some convolution. But if you refer to having to prefix you outer variables with scope. then this would be the same as claiming that the explict use of self is convoluted, which is a valid opinion, so fair enough, but I can't say that I agree. I didn't mean to call into question. I didn't understand the advantage of the added complexity of your second example over the first. It should also be noted that although I have to declare and create a scope object. My method doesn't require the attributes passed back from the inner function be pre-declared, should I during coding realise that I need to return another attribute I just assign it in the inner function and use it in the outer function. I would count that as less convoluted, YMMV. That is certainly a very interesting aspect. And speaking of convoluted, what about efficiency? There is much talk of efficiency on this forum. I (crudely) benchmark your previous example approximately three times slower than a simple inner function taking and returning three parameters. It was actually the aspect of increased efficiency that prompted me to play with the idea of allowing direct outer writes. Did you have optimisation turned on ? No. I did a hundred thousand loops over each in IDLE using xrange. As I see it there should be no reason an optimiser couldn't transform my code into the same code we might expect from your outer keyword example, as the scope object's type and attributes are all contained within (thus known to) the outer function defenition. I doubt that very much. The 'outer' keyword would give me the choice between two alternatives. Such a choice can hardly be automated. Wether CPython's optimiser does this or not, I don't know. Thats -2 import-this points already. Which ones are the two? Explicit is better than implicit. There should be one-- and preferably only one --obvious way to do it. Rob.

I'm not quite sure what your asking, but I'll give it a shot.

I don't know how to make this structure immutable... Pickle it? Seems very inefficient to me... Every time I pass a variable now I will worry that it will be changed by the function... I haven't worried about things like this since the very early days of BASIC I don't know.. maybe I have more to learn. You do. Firstly, learn to leave your paranoia outside your programming life. If a function or method makes undocumented changes to its mutable parameters then it needs changing (or its documentation does).

Re: Why can't you assign to a list in a loop without enumerate?
In the following code snippet, I attempt to assign 10 to every index in the list a and fail because when I try to assign number to 10, number is a deep copy of the ith index (is this statement correct?). Sorta...just like with function parameters, there are mutables and immutables. a = [1,2,3,4,5] for number in a: ... number = 10 ... a [1, 2, 3, 4, 5] Just as with a function (currently discussed on another thread recently), you have the following behavior: def a(x): ... x = 42 ... deb b(x): ... x.append(42) ... g = 1 h = [1] a(g) b(h) g 1 h [1, 42] you have similar behavior: a = [[1],[2],[3],[4],[5]] for thing in a: ... thing.append(10) ... a [[1, 10], [2, 10], [3, 10], [4, 10], [5, 10]] Lists/sets/etc are mutable. Strings, numbers, So, I have to resort to using enumerate to assign to the list: for i, number in enumerate(a): ... a[i] = 10 ... a [10, 10, 10, 10, 10] This would commonly be written with a list comprehension: a = [10 for _ in a] or a = [10] * len(a) or, if that was a general case of something more specific with some if brains behind it, you can do things like a = [odd(v) and 10 or v for v in a] to only change them to 10 where the value is odd. My question is, what was the motivation for returning a deep copy of the value at the ith index inside a for loop instead of the value itself? Also, is there any way to assign to a list in a for loop (with as little code as used above) without using enumerate? As stated above, it returns the item...if it's mutable, you can mutate it. If it's an immutable (like your numbers), you just change the variable in the local scope of the loop. -tkc -- http://mail.python.org/mailman/listinfo/python-list

No. There is no copying involved. Before the assignment, number is a reference to the object to which the ith element of the list also refers. After the assignment you have rebound the variable 'number' so it refers to the value 10. You won't affect the list that way.

N.B. This last form leaves the original list unchanged: if you really need to mutate it in place assign to a[:] as in the first example, but if you are changing all elements in the list then you usually want a new list. -- http://mail.python.org/mailman/listinfo/python-list

Seems like your statement is *not* correct.
a = [1,2,3,4,5]
for number in a:
... number = 10
Note that you are *not* assign(ing) 10 to every index in the list
here. Rebinding the local name 'number' in each iteration only makes
this name refer to another object (implying of course loosing the
reference to the current list element). Then - on the following
iteration - the name 'number' is rebound to the next object in the list.
a
[1, 2, 3, 4, 5]
for foo in foos:
... original = foo
... foo = Foo(10)
... print original : %s - foo : %s % (original, foo)
...
original : foo 0 at 47281508865040 - foo : foo 10 at 47281508864144

So, I have to resort to using enumerate to assign to the list:
Yes. That's still far better than having to manually check for sequence
boundaries and track current index.
for i, number in enumerate(a):
... a[i] = 10
...
a
[10, 10, 10, 10, 10]
Just for the record: the notation 'a[x] = y' in fact calls
'a.__setitem__(x, y)'. It's really just calling a method that alters the
state of object a.
My question is, what was the motivation for returning a deep copy of
the value at the ith index inside a for loop instead of the value
itself?
Forget about values. Think objects.
i = 10
i.__class__
type 'int'
dir(i)
['__abs__', '__add__', '__and__', '__class__', '__cmp__', '__coerce__',
'__delattr__', '__div__', '__divmod__', '__doc__', '__float__',

Integrating Python with Fortran

I'm aware of resources like the F2Py Interface generator, but this only lets me access the Fortran modules I need in Python. I'm wondering if there's a way to generate the .o files from Python (maybe using py2exe?) and then link the .o file with the rest of the Fortran project using something like gcc.

Please take a look at the extending and embedding tutorial. This explains you how to integrate Python code into a C application. If you think this could work for you if just your application was C, I think the Python-Fortran people can give you precise instructions on how to integrate Python code into a Fortran program. In the simplest embedding example, you just link the Python VM itself into the hosting application. The actual Python files stay on disk, and invoking a Python function from C/Fortran will just end up doing a regular Python import (with searching sys.path and everything). If, for packaging reasons, you prefer to have the Fortran program stand-alone, I recommend to use freeze. freeze gives you indeed .o files for Python files, plus a global table of all frozen modules. Then, when doing an import, the interpreter won't go to disk anymore, but it will import the byte code from memory (it still would be a regular import operation). Freeze, of course, requires you to recompile/relink your application every time you change a Python source file. HTH, Martin -- http://mail.python.org/mailman/listinfo/python-list

If you want to open the file for writing just open it with append mode. open(¨filename, a).

Or (doesn't make much sense, but still) try to open it for reading and python will throw an IOException which you can catch and handle.

Re: Python tools for managing static websites?
Chris Pearl wrote: Are there Python tools to help webmasters manage static websites? I'm talking about regenerating an entire static website - all the HTML files in their appropriate directories and sub-directories. Each page has some fixed parts (navigation menu, header, footer) and some changing parts (body content, though in specific cases the normally fixed parts might change as well). The tool should help to keep site editing DRY every piece of data, including the recurring parts, should exist only once. The above should be doable with any decent templating tool, such as those forming part of most CMSes and full-stack web-frameworks. Normally I might have just resorted to a CMS/web-framework, running locally on the webmaster's station, with the only addition being a mechanism for generating all pages composing the site and saving them as files. But such a solution might not be enough, as the system I'm looking for must be able to control the physical traits of the website as a collection of files - e.g., creation and distribution of files among several physical directories and subdirectories. Chris, If you don't mind me pimping my own static website generator, you might find HRL useful: http://www.aerojockey.com/software/hrl On one hand, it's like an ordinary templating engine in that you can define macros and variables and such, and stick them into documents. For example, define a sidebar macro in the file macro.hri: macro name=sidebar ul liFirst menu entry/li liSecond menu entry/li liThrid menu entry/li /ul /macro This creates a new sidebar tag that expands to the macro definition. You can use this macro in your main document file: include file=macro.hri sidebar However, HRL is much more powerful than a simple templating system, because it can embed Python code to be run during page generation. Here's a very simple example: python import time hrl.doc.write(Page last generated on %s % time.asctime(time.localtime())) /python Thus, unlike most templating engines, HRL can adapt very well to unusual situations. You can embed the Python scriptlet into macro definitions to create very powerful macros. For instance, you could write a sidebar macro to automatically disable the link to the current page--impossible with a simple text-substitution engine. Even more powerful uses are possible. You could write a macro that inserts information from a database into the page (which sounds kind of like what you mentioned). On the downside, it's not exactly hip to the latest web trends. It uses sgmllib for input, bleagh. The list of HTML tags it knows about is vintage 1998. (One of my design goals was freedom to be sloppy with closing tags. HRL keeps track of and automatically closes tags when appropriate, but it doesn't know about tags like embed.) And it's not any sort of enterprise-quality content management. It's just a templating engine with power. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
