As Gabriel has suggested, spend a little more time going through the

I'll give you an example: I want to extract the text between the
following span tags in a large HTML source file.

soup = BeautifulSoup(urlopen('http://www.someurl.tld/'))

One can even use ElementTree, if the HTML is well-formed. See below.
However if it is as ill-formed as the sample (4th td element not
closed; I've omitted it below), then the OP would be better off
sticking with Beautiful Soup :-)

irclib problems
I'm playing around with the 'irclib' library working with the first
example at
http://www.devshed.com/c/a/Python/IRC-on-a-Higher-Level-Concluded/
When copying the example verbatim and running it from a console it works
flawlessly. It connects to the server, join the channel and sits there
'forever'...
However, I want to use it in a PyQt application and have done the following.
I have created a module named 'irclibtest.py' that looks like this:
### irclibtest start ###
import irclib
irclib.DEBUG = True
class Conn:
def __init__(self):
# Network information
self.network = '192.x.x.x'
self.port = 6667
self.channel = '#test'
self.nick = 'IRClibt'
self.name = 'Python Test'
# Subclass SimpleIRCClient
class ClientClass ( irclib.SimpleIRCClient ):
pass
# Create an instance of ClientClass and connect.
self.client = ClientClass()
self.client.connect ( self.network, self.port, self.nick,
ircname = self.name )
self.client.connection.join ( self.channel )
##irclibtest end ###
And my main Qt application:
### Main application start ###
#!/usr/bin/python
# -*- coding: utf-8 -*-
import sys, irclib
from PyQt4 import QtGui , QtCore
from tircUI import Ui_MainWindow
from irclibtest import Conn
class TircMain(QtGui.QMainWindow , Conn):
def __init__(self):
QtGui.QMainWindow.__init__(self )
Conn.__init__(self)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.connect(self.ui.sendButton, QtCore.SIGNAL(clicked()),
self.doSend)
def doSend(self):
''' Just a test to see if I can send to channel'''
self.client.connection.privmsg('#test' , 'Test text')
if __name__ == __main__:
app = QtGui.QApplication(sys.argv)
f = TircMain()
f.show()
sys.exit(app.exec_())
### Main application end ##
The problem is that this pings out (PING timeout). As far as I
understand it rclib.SimpleIRCClient is supposed to handle PING-PONG with
the server so I don't understand why it does not in my Qt test, but it
does 'raw'.
I can send to the channel right up to the point it times out by the way.
Anyone know what I'm missing here?
Thanks

As is often the case with Python, and indeed many open source projects, the people who are knowledgeable enough to do such things usually don't need to do them, as their setup already works just fine. So you're saying the knowledgeable people's attitude is fuck everyone else as lomg as it's not MY problem? And you people complain about Microsoft. Am I one of those people? You don't exactly make it clear. I'm talking about the people who complain about Microsoft making the VC6 compiler no longer legally available and yet are so irresponsible that they use it for the latest release. I think you'll find those two sets are disjoint. But yes, there is a lot of well, it works for me going around. If you do that long enough, people stop complaining, so people wrongly assume there's no longer a problem. This is partly why Python has various warts on Windows and why the standard libraries are oddly biased, why configuring Linux almost always ends up involving hand- editing a .conf file, why the leading cross-platform multimedia library SDL still doesn't do hardware graphics acceleration a decade after such hardware became mainstream, and so on. However, the difference between the open-source people and Microsoft is the the open-source people aren't being paid by you for the use of their product, so they're not obligated in any way to help you. This argument has become tiresome. The Python community wants Python to be a big fish in the big pond. That's why they make Windows binaries available. ? I would suggest rather that the Python community (by which you apparently mean the developers) hope that the fruits of their labours will be used by as wide a cross-section of computer users as possible. The goals of open source projects are not those of commercial product developers: I and others wouldn't collectively put in thousands of unpaid hours a year to make a commercial product better and protect its intellectual property, for example. After all, they have already given freely and generously, and if they choose not to give more on top of that, it's really up to them. Right. Get people to commit and then abandon them. Nice. Anyone who committed to Python did so without being battered by a multi-million dollar advertising campaign. Multi-million dollar ad campaigns mean nothing to me. I committed to Python because it's a great language. I've dabbled in perl, Visual BASIC, UBASIC, REXX, Java, Scheme, C and C++ but Python is the one I use. The Python Software Foundation has only recently dipped its toes in the advocacy waters, with results that are still under evaluation. And the use of the Microsoft free VC6 SDK was never a part of the official means of producing Python or its extensions, it was a community-developed solution to the lack of availability of a free VS-compatible compilation system for extension modules. I agree that there are frustrations involved with maintaining extension modules on the Windows platform without having a copy of Visual Studio (of the correct version) available. One of the reasons Python still uses an outdated version of VS is to avoid forcing people to upgrade. Any such decision will have fallout. Such as anyone who tries to get in the game late. An update is in the works for those using more recent releases, That's good news, although the responsible thing to do was not relaease version 2.5 until such issues are resolved. but that won't help users who don't have access to Visual Studio.

That can be solved by throwing money at the problem. But money doesn't help when the solution is on the far side of the moon. I see your problem, but I don't know what I can do to help you. There were also, as I remember it, issues with the updated version of Visual Studio being non-conformant with standards in some significant way, but I never took part in the discussions on those issues.

I really don't think you help your argument by trying to draw parallels between the problems of compiler non-availability and those of a population subject to random genocide.

Luckily, unlike the Kurds, my situation had a happy ending, someone else compiled the fixed GMPY source and made a 2.5 Windows version available. But can anyone say what will happen the next time? Presumably not. I presume you have been reporting your bugs through the Sourceforge project to keep the developers in touch with the issues you have found? Normally a package's maintainers will produce updated installers, but this behaviour is unreliable and (no pun intended) patchy sometimes. The best I feel I can do is raise these things on occasion, on the off-chance that I manage to catch the attention of someone who is altruistic, knowledgeable, and who has some spare time on their hands! Someone who, say, solved the memory leak in the GMPY divm() function even though he had no way of compiling the source code? Just think of what such an altruistic, knowedgeable person could do if he could use the current VC compiler or some other legally available compiler. Your efforts would probably be far better spent trying to build a back-end for mingw or some similar system into Python's development system, to allow Python for Windows to be built on a regular rather than a one-off basis using a completely open source tool chain. No, as I said elsewhere, I'm not a software developer, I'm an amateur math researcher. My efforts are best spent as an actual end user to find and report bugs that the developers never see.

You missed the point of the analogy. The US government suggested to the oppressed tribes in Iraq that they should rise up and overthrow Saddam Hussein at the end of the first Gulf War. And what did the US government do when they rose up? Nothing. They were left to twist in the wind. Both the southern Iraqis (mostly so-called marsh Arabs and Shiites) and the northern Kurds rose up against Saddam Hussein. After the Kurdish rebellion failed, the US and UK belatedly provided them with aid, lots of aid, and kept the northern no-fly zone going until it was no longer relevant (2003, the second invasion of Iraq). It was the southern Iraqis who were left to be slaughtered. Although technically there was a no-fly zone in the south, it wasn't enforced when it really counted -- while the rebellion was in full force, the Iraqi government asked the US for permission to fly into the south. Permission was given, and the Iraq air force used combat aircraft against the rebels. Unlike the Kurds, they got no aid, neither money nor military support. The end result was that the southern Iraqs were hung out to dry, while the Kurds ended up a virtually independent state-within-a-state, with their own government, their own army, and US and British aircraft protecting them.

Problem with reimporting modules
I'm currently investigating a problem that can hit you in TurboGears when Kid template modules are reloaded in the background, because in certain situations, global variables suddenly are set to None values. I tracked it down to the following behavior of Python. Assume you have a module hello.py like that: hello. py greeting = 'Hello!' def print_hello(): print greeting --- Now run the following code: from hello import print_hello print_hello() import sys del sys.modules['hello'] # delete module import hello # recreate module print_hello() The second print_hello() prints None instead of Hello!. Why is that? I had expected that it either prints an error or print Hello! as well. Is this intended behavior of Python? -- Christoph -- http://mail.python.org/mailman/listinfo/python-list

Hope that helped. This code assumes there aren't any td tags with
header=col2_1 that come before the value you are trying to extract.
There's several ways to do things in BeautifulSoup. You should play

Re: How to find all the same words in a text?
In order to find all the words in a text, you need to tokenize it first. The rest is a matter of calling the count method on the list of tokenized words. For tokenization look here: http://nltk.sourceforge.net/lite/doc/en/words.html A little bit of warning: depending on what exactly you need to do, the seemingly trivial taks of tokenizing a text can become quite complex.

Multi-million dollar ad campaigns mean nothing to me. I committed to Python because it's a great language. I've dabbled in perl, Visual BASIC, UBASIC, REXX, Java, Scheme, C and C++ but Python is the one I use. Yes, but your decision must surely have been an informed one, and there must surely be reasons why Python remains your choice. The Python Software Foundation has only recently dipped its toes in the advocacy waters, with results that are still under evaluation. And the use of the Microsoft free VC6 SDK was never a part of the official means of producing Python or its extensions, it was a community-developed solution to the lack of availability of a free VS-compatible compilation system for extension modules. I agree that there are frustrations involved with maintaining extension modules on the Windows platform without having a copy of Visual Studio (of the correct version) available. One of the reasons Python still uses an outdated version of VS is to avoid forcing people to upgrade. Any such decision will have fallout. Such as anyone who tries to get in the game late. I'm afraid it does seem to work out like that, yes. An update is in the works for those using more recent releases, That's good news, although the responsible thing to do was not relaease version 2.5 until such issues are resolved. Well that would be an issue for the release team. I'm not sure what Anthony Baxter (the release manager) would have to say in response to this point. Possibly something like: I realize you're a Windows user, and a Windows user with an AOL email address at that, so it may come as a shock to learn that the computer industry doesn't start and finish on Windows. I don't see why the needs of Windows users like yourself should come ahead of the needs of users on Mac OS, Linux, Solaris, etc. - Steven D'Arpano I would hope that it would instead be that the needs of all users are equal. but that won't help users who don't have access to Visual Studio. That can be solved by throwing money at the problem. But money doesn't help when the solution is on the far side of the moon. I see your problem, but I don't know what I can do to help you. Well, that was the point of this, to get people to see the problem. There were also, as I remember it, issues with the updated version of Visual Studio being non-conformant with standards in some significant way, but I never took part in the discussions on those issues. Yes, it's occasionally very frustrating to the rest of us, but that's life. As the Kurds are well aware. I really don't think you help your argument by trying to draw parallels between the problems of compiler non-availability and those of a population subject to random genocide. You missed the point of the analogy. Perhaps because it wasn't a very good one? The US government suggested to the oppressed tribes in Iraq that they should rise up and overthrow Saddam Hussein at the end of the first Gulf War. And what did the US government do when they rose up? Nothing. They were left to twist in the wind. Try to keep things in perspective, please. See if you can see the similarity. I buy into Python. I spend a lot of effort developing a math library based on GMPY to use in my research. I discover a bug in GMPY and actually go to a lot of effort and solve it. But _I_ can't even use it because I've been left to twist in the wind by the fact that Python 2.5 for Windows was built with an obsolete compiler that's not even available. Luckily, unlike the Kurds, my situation had a happy ending, someone else compiled the fixed GMPY source and made a 2.5 Windows version available. But can anyone say what will happen the next time? Presumably not. I presume you have been reporting your bugs through the Sourceforge project to keep the developers in touch with the issues you have found?

And what did the US government do when they rose up? Nothing. They were left to twist in the wind. Both the southern Iraqis (mostly so-called marsh Arabs and Shiites) and the northern Kurds rose up against Saddam Hussein. After the Kurdish rebellion failed, the US and UK belatedly provided them with aid, lots of aid, and kept the northern no-fly zone going until it was no longer relevant (2003, the second invasion of Iraq). It was the southern Iraqis who were left to be slaughtered. Although technically there was a no-fly zone in the south, it wasn't enforced when it really counted -- while the rebellion was in full force, the Iraqi government asked the US for permission to fly into the south. Permission was given, and the Iraq air force used combat aircraft against the rebels. Unlike the Kurds, they got no aid, neither money nor military support. The end result was that the southern Iraqs were hung out to dry, while the Kurds ended up a virtually independent state-within-a-state, with their own government, their own army, and US and British aircraft protecting them.

Adding an XML fragment as a child node in a pre-existing Element tree
Hi, I'm using ElementTree for some RSS processing. The point where I
face a problem is that within an item/item I need to add another
child node (in addition to link etc) which is a well-formed XML
document (Chemical Markup Language to be precise).
So my code looks like:
import cElementTree as ET
c = open('x.cml').readlines()
c = string.join(c)
cml = ET.XML(c)
Now I also have the following code:
def addItem(self, title, link, description, cml = None):
RSSitem = ET.SubElement ( self.RSSchannel, 'item' )
ET.SubElement( RSSitem, 'title' ).text = title
ET.SubElement( RSSitem, 'description' ).text = description
What I'm confused is how I can add the cml Element object that I
generated, to the RSSitem as a child node.
Do I need to manually traverse the tree of the CML document and add it
one by one to the RSSitem as a child node? Or is there a smarter way
to do this?
Any pointers would be greatly appreciated
Thanks,
Rajarshi

SubElement is just a convenience function for creating a new element and

Re: Problem with reimporting modules

I don't want to rewrite everything since it's a pretty complex thing with modules which are compiled from templates which can depend from other templates etc... If you remove the module from sys.modules, when you import it again you end up with a *new*, fresh, module object, unrelated to the original one. Quoting your original message again: I tracked it down to the following behavior of Python. Assume you have a module hello.py like that: hello. py greeting = 'Hello!' def print_hello(): print greeting --- Now run the following code: from hello import print_hello print_hello() import sys del sys.modules['hello'] # delete module import hello # recreate module print_hello() The second print_hello() prints None instead of Hello!. Why is that? Notice that you are mixing references here. You first import print_hello from hello, and after deleting the module, you import hello (not print_hello). And you expect that your old reference to print_hello now refers to the new function. The whole point of reloading/reimporting a module is to get the *new* contents, but that only works if you refer to things using the module.function notation, not if you hold a reference to the function (which will always be the original function). In short, your code should be: import hello hello.print_hello() import sys del sys.modules['hello'] import hello hello.print_hello() or, using reload: import hello hello.print_hello() reload(hello) hello.print_hello() If you think that always typing module.function is too much - well, don't try to reload modules then :) Somewhere I read that at Google the policy is to always import modules, never functions, and this may be a good reason for it. If you want to know the details: print_hello doesn't hold a reference to the containing module, only to its namespace, in the func_globals attribute. When you delete the last reference to the module, it gets destroyed. At that time, all values in the module namespace are set to None (for breaking possible cycles, I presume). print_hello now has a func_globals with all names set to None. (Perhaps the names could have been deleted instead, so print_hello() would raise a NameError, but I'm just describing the current CPython implementation) -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list

Regexps and lists
I don't know enough to write an R.E. engine so forgive me if I am
being naive.
I have had to atch text involving lists in the past. These are usually
comma separated words such as
egg,beans,ham,spam,spam
you can match that with:
r(\w+)(,\w+)*
and when you look at the groups you get the following
import re
re.match(r(\w+)(,\w+)*, egg,beans,ham,spam,spam).groups()
('egg', ',spam')
Notice how you only get the last match as the second groups value.
It would be nice if a repeat operator acting on a group turned that
group into a sequence returning every match, in order. (or an empty
sequence for no matches).
The above exaple would become:
import re
re.newmatch(r(\w+)(,\w+)*, egg,beans,ham,spam,spam).groups()
('egg', ('beans', 'ham', 'spam', ',spam'))

Alright. I have tried everything I can find, but am not getting

What is show is only a small section.
I want to extract the 33,699 (which is dynamic) and set the value to a
variable so that I can insert it into a database. I have tried parsing
the html with pyparsing, and the examples will get it to print all
instances with span, of which there are a hundred or so when I use:
for srvrtokens in printCount.searchString(printerListHTML):
print srvrtokens
If I set the last line to srvtokens[3] I get the values, but I don't
know grab a single line and then set that as a variable.
So what you are saying is that you need to make your pattern more
specific. So I suggest adding these items to your matching pattern:
- only match span if inside a td with attribute 'headers=col2_1'
- only match if the span body is an integer (with optional comma
separater for thousands)
This grammar adds these more specific tests for matching the input
HTML (note also the use of results names to make it easy to extract
the integer number, and a parse action added to integer to convert the
'33,699' string to the integer 33699).

I don't know enough to write an R.E. engine so forgive me if I am

I have had to atch text involving lists in the past. These are usually
comma separated words such as
egg,beans,ham,spam,spam
you can match that with:
r(\w+)(,\w+)*
You *can*, but why do that? What are you trying to achieve? What is
the point of distinguishing the first element from the remainder?
See if any of the following do what you want:
| s = egg,beans,ham,spam,spam
| s.split(',')
| ['egg', 'beans', 'ham', 'spam', 'spam']
| import re
| re.split(r,, s)
| ['egg', 'beans', 'ham', 'spam', 'spam']
| re.split(r(,), s)
| ['egg', ',', 'beans', ',', 'ham', ',', 'spam', ',', 'spam']
and when you look at the groups you get the following
import re
re.match(r(\w+)(,\w+)*, egg,beans,ham,spam,spam).groups()
('egg', ',spam')
Notice how you only get the last match as the second groups value.
It would be nice if a repeat operator acting on a group turned that
group into a sequence returning every match, in order. (or an empty
sequence for no matches).
The above exaple would become:
import re re.newmatch(r(\w+)(,\w+)*,
egg,beans,ham,spam,spam).groups()
('egg', ('beans', 'ham', 'spam', ',spam'))
And then what are you going to do with the answer? Something like
this, maybe:
| actual_answer = ('egg', ('beans', 'ham', 'spam', ',spam'))
| [actual_answer[0]] +list(actual_answer[1])
| ['egg', 'beans', 'ham', 'spam', ',spam']
1, Is it possible?
Maybe, but I doubt the utility ...
do any other RE engines do this?

No.

Help with Optimization of Python software: real-time audio controller
I've been working on a Python-based music training application for a few months, and have recently run into what I believe are some basic limitations (or at least constraints) of Python with regards to timing. I'll try and give a decently thorough description, and hopefully some of you can process this with your knowledge and help steer me in the right direction. As mentioned above, my application deals with music training. I have a Tkinter GUI, which communicates via pyserial with an external device I built myself. The code reads in a MIDI file and converts the song to output data for the external device and the GUI, all adjusted to the user-selected tempo. While the MIDI file is playing, there are 4 main actions the code must take: 1) Send output data signals out to the external hardware. 2) Poll the input from the external hardware device for incoming keypresses. If detected, then the play the sound corresponding to that key. 3) Start and keep a metronome running for the durations of the song. 4) Update GUI I'm able to get all the above accomplished through the use of threads and a top-level loop (for updating the Tkinter GUI - if you've worked with threads and Tkinter, then you know that you can't update a Tkinter GUI from a thread, but instead have to do it on the top level loop). While running, I have the following threads implemented : 1) song processing thread - this thread steps incrementally through a data matrix (the output data), and updates two variables: GUI_vars and Device_vars 2) metronome thread - this thread starts at the same time as thread #1, and outputs a beep to the audio chain 3) poll input thread - this thread loops continually, looking for data on the serial Input. When data is found, it starts playing the sound corresponding to that key until a note off signal is received 4) top-level recursive loop (technically not a thread) for updating GUI and calling Serial Write subfunction. This loop monitors GUI_vars and Device_vars, updating the GUI and writing out to the device when either variable has changed Currently, I have all of the above working, although I'm running into some serious timing issues. When I run the program, I get irregular timing for my metronome (if it sounds at all), as well as irregular timing in writing to the external device. It's extremely crucial that threads #1 #2 are executed as close to real-time as possible, as they form the core of the song, and their elements can't be delayed without messing the song up considerably. I've read up quite a bit on different optimization methods in Python, but am not sure which direction to head. I've checked out profile, Psyco, Pyrex, as well as just porting everything over to C. Since I'm on a Mac (Power PC), I can't use Psyco. And doing any of the others seemed like a big enough project that I should really ask someone else before I embark. So, for a music-based application where it's crucial to have real-time execution of serial writeouts and audio, as well as keeping a continual poll on the input from the same portcan this be done successfully in Python? Does using Tkinter have anything to do with my timing issues? Would it benefit me to move over to wxPython (something I've been considering doing)? As for the metronome, should I incorporate the metronome thread into the song processing thread, since both are dealing with events whose timing is crucial? I'm a relative newbie (this is my first Python project) to Python, so any help is GREATLY appreciated! Also, just for reference, here's a list of the modules I'm using and my system info: Audio: SndObj Ser com: pyserial GUI: Tkinter System: Apple PowerBook G4 (PowerPC), Mac OS 10.4, Python 2.4.4 Thanks, Craig Lewiston -- http://mail.python.org/mailman/listinfo/python-list

Thanks, Frank Hi Frank, Take a look at the demos in OpenGL, particularly: OpenGL-ctypes/OpenGL/Demo/GLUT/tom/conesave.py which is a little GLUT application that renders into a GLUT windows and then allows you to save it. That's raster operation though (i.e. produces a PNG or JPG). Raster operations can only save a portion of the screen as rendered, so if you want a higher resolution image you need to make a larger window. If you want to get more advanced you can try using an off-screen buffer (pbuffer or MESA) for the rendering, which may (depending on implementation) allow for higher resolutions. If you want a true vector graphic (PS, EPS) you'll need to use something like GL2PS. http://www.geuz.org/gl2ps/ HTH, Mike -- Mike C.
