can i create a case insensitive string column in sqlalchemy? im using sqlite, and theres probaby a way to do it through DB by changing collation, but i want to keep it in sqlalchemy/python.
I have an application that displays some HTML in a QWebview, which references images on the local file system. This works fine directly running the python. When compiling via py2exe, the images no longer load. Google doesn't seem to know the answer, any ideas?
I'm researching how to best extend a C++ application with scripting capability, and I am looking at either Python or JavaScript. User-defined scripts will need the ability to access the application's data model.
Have any of you had experiences with embedding these scripting engines? What are some potential pitfalls?
I have a jython servlet as part of a large application running in tomcat5. I tested a few Spring Framework classes and create the objects in the Jython servlet. When I try to create objects of classes in the application I catch an Exception message "No visible constructors for class". These java classes do have a public constructor class, such as:
public SchoolImpl() {
}
I create the object in python:
from com.dc.sports.entity import SchoolImpl
...
school = SchoolImpl()
What am I doing wrong?
The Selenium setup.py can be found at http://code.google.com/p/selenium/source/browse/trunk/setup.py.
When running "python setup.py sdist" the "firefox/test/py" directory
is ignored for some reason though it's
mentioned in the "package_dir" and in "packages".
Any ideas why it's ignored?
Hey,
I have a directory full of images that I would like to resize to around 60% of their original size.
How would I go about doing this? Can be in either Python or Perl
Cheers

What would be a good way to create logs (with python logging module) inside a constant running loop, without producing a large amount of useless log-files?
An example would be a loop that constant list a folder, and does some action when it sees a file of a specific type.
I want to log that no files were found, or files were found but of a wrong type, without logging that same line constantly for each folder check, as it might run many times a second.
I have alignment file and long record in it. Suppose while displaying to an end user i want to show Sequence ID and 50 sequences in each line and continue further till the end of file.
Can anyone suggest me algorithm or example code in python.
Thanks in advance
I am planning to use py2exe to make an application developped with Python 2.6.
It seems that my app need the VC redistribuables : http://www.py2exe.org/index.cgi/Tutorial#Step5
I've read this tutorial and the redistribuables license agreement and I am not sure if I can freely redistribute these files with my program. (I don't have VS2008 license)
Can I bundle the redistribs into an installer and make the installation transparent for the user or do they have to download the files by their own from Microsoft website?
Thanks in advance
I'm trying to do this:
commands = { 'py': 'python %s', 'md': 'markdown "%s" "%s.html"; gnome-open "%s.html"', }
commands['md'] % 'file.md'
But like you see, the commmands['md'] uses the parameter 3 times, but the commands['py'] just use once. How can I repeat the parameter without changing the last line (so, just passing the parameter one time?)
I want to start learning OpenGL but I don't really want to have to learn another language to do it. I already am pretty proficient in python and enjoy the language. I just want to know how close it is to the regular api? Will I be able to pretty easily follow tutorials and books without too much trouble?
I know C++ gives better performance, but for just learning can I go wrong with PyOpenGL?
Thanks alot
Python and Matlab quite often have integer date representations as follows:
733828.0
733829.0
733832.0
733833.0
733834.0
733835.0
733836.0
733839.0
733840.0
733841.0
these numbers correspond to some dates this year. Do you guys know which function can convert them back to YYYYMMDD format?
thanks a million!
I swear this should be so easy... Why is it not? :(
In fact, I want to combine 2 parts of the same array to make a complex array:
Data[:,:,:,0] , Data[:,:,:,1]
These don't work:
x = np.complex(Data[:,:,:,0], Data[:,:,:,1])
x = complex(Data[:,:,:,0], Data[:,:,:,1])
Am I missing something? Does numpy not like performing array functions on complex numbers? Here's the error:
TypeError: only length-1 arrays can be converted to Python scalars
Cheers
If I wanted a single word that meant "conforming to Java language conventions", what would that be? Python has the term "pythonic". Would it be "javaish"?
I'm trying to install this:
http://www.coderholic.com/pywebshot-generate-website-thumbnails-using-python/
I've googled a lot,and still can't make it work(gtk runtime has been installed successfully(gtk-demo works),but it still reports can't find MSVCR80.dll,this should be because that I have installed Microsoft Visual Studio 9.0?),
each time it reports ImportError: DLL load failed,MSVCR80.dll is not found..
How to make an application that needs MSVCR80.dll work when I've already installed Microsoft Visual Studio 9.0?
Or :
How to make _gtk.pyd use MSVCR90.dll instead of MSVCR80.dll?
Hi,
I need to write a program to scrape forums.
Should I write the program in Python using the Scrapy framework or should I use Php cURL?
Also is there a Php equivalent to Scrapy?
Thanks
Are there any libraries or frameworks that provide the functionality of a browser, but do not need to actually render physically onto the screen?
I want to automate navigation on web pages (Mechanize does this, for example), but I want the full browser experience, including Javascript. Thus, I'd like to have a virtual browser of some sort, that I can use to "click on links" programmatically, have DOM elements and JS scripts render within it, and manipulate these elements.
Solution preferably in Python, but I can manage others.
Im trying to count how many repeated lists there are inside a list. But it doesnt work the same way I could count repeated elements in just a list. Im fairly new to python, so apologies if it sounds too easy.
this is what i did
x= [["coffee", "cola", "juice" "tea" ],["coffee", "cola", "juice" "tea"]
["cola", "coffee", "juice" "tea" ]]
dictt= {}
for item in x:
dictt[item]= dictt.get(item, 0) +1
return(dictt)
Hi guys, I have to get linux distro name from python script. There is dist method in platform module:
import platform
platform.dist()
But it returns
>>> platform.dist()
('', '', '')
Under my Arch Linux. Why? How can I get the name.
p.s. I have to check whether the distro is debian-based.
I'm trying to get the first href attribute in a page using Selenium RC (in Python):
sel.get_text("xpath=//@href")
this returns an empty string.
However, an identical xpath on the same page inside Firefox (using the "View XPath" extension) yields the correct value.
I've tried fiddling with it, but the same happens for other attributes (eg @class) -- is there something awfully wrong with selenium or am I overlooking something trivial here?
For better description,

Look at WxPython App., which is align to the bottom right of screen. How to I position my main frame because screen width is different on each pc?
For Better Understanding, I want to pop-up small window like Digsby and FeedNotifier use!
i think both use python!!
isk-daemon software permits setting feature parameters?
I download desktop version and apparently not!
There are alternative libraries or software which is not all automatic?
I have a set of images and i only want to pick up an image, extract some features and compare them with this set of image, basing on a similarity metric that give me a percentage result like isk-daemon but with more freedom in settings, better in python!
Hi,
I need huffman code(best in python or in java), which could encode text not by one character (a = 10, b = 11), but by two (ab = 11, ag = 10). Is it possible and if yes, where could i find it, maybe it's somewhere in the internet and i just can'd find it?
