Re: GUI components in python
Hi Janaki, Python will mostly use either the pygtk library or pyqt library for any rich and production quality GUI. So you must try figuring out if either of these 2 libraries are used. Other than this, there is tkinter which i guess comes with Python as default. Happy hacking. Krishnakant.

can I use element tree for handling special characters in xml text?
Hello all. I have been waiting a lot to ask this question and I did ask some days back but probably could not put it the proper way. I want to know how I can safely include special characters like or in xml text? For example I store a small xml file containing list of organisations. Many names have an in the name as in brian turner. so the xml noad will be orgname brian turner /orgname But I know this won't work directly. my code naturally fails when I try to insert such data. Can any one suggest the right way of parsing this kind of strings and treat like characters as part of the literal string? Hope my question is clear this time. Happy hacking.

how to get Python to insert special characters in an xml file?
Hello all. I am currently developing a python application which reads and writes some data to an xml file. I use the elementTree library for doing this. My simple question is that if I have some thing like as in kk company as organisation name, how can I have Python take this as a litteral string including the sign and put in the orgname /orgname tag? Even same applies while reading the file. I would like to have the come as a part of the literal string. Happy hacking. Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list
can I package a distutil based python app in deb?
Hello all, I guess the subject line says it all. I want to package a python app to deb. I have 3 interesting issues with it. 1, I would want it to run on Ubuntu 10.04, Ubuntu 10.10, Ubuntu 11.04 and Debian 5. 2, the package depends on another python package which is also distutil based. 3, The second package needs to run in a virtual environment. This means that I not only have to figure out the dependencies but also have the deb to include a script to get the virtual environment script, then create one for the package, then download all dependencies (Pylons 0.9.7 in this case along with report lab) and finally put the package into this virtual environment.

no line breaks in xml file with elementTree
Hello all. I want to know if there is a way to have the ElementTree module write to an xml file with line breaks? I find that when I use the write function from the module on a tree object, the resulting file has no line breaks. I don't want to use prittyprint because it is adding extra tabs to the file and they are either counted as extra nodes or in case of element.text with elementtree, they are rendered as a part of the text, both being impractical results. So is there a middle approach where we can have some thing similar to prityprint but without the extra tabs and yet having a properly line breaked xml file? Further more, I just was curious why elementtree is not having the namespace facility? xml.dom.minidom has a way to generate tags with namespaces. Any thing similar in elementTree? happy hacking.

is elementTree really a part of python 2.6?
Hello all, Some days back I had asked a few questions about parsing xml files using python. I have tryed dom.minidom module but I did not like the prittyPrint way of writing nodes. There were many other things I did not quite like about dom.minidom, so now trying to use elementTree. But to my surprise, I could not import xml.elementtree in my default python 2.6 setup. is it possible that I have broken some thing? I had to later on do an easy_install for elementree. But I hear that elementtree is a part of python? So has my import gone wrong? or is some thing broken in my python setup? happy hacking.

Re: Should I Learn Python or Ruby next?
Ruby is a nice language to learn, but I seem to find it less matured. That might be my own personal perception.

Besides ruby is more popular due to the rails attached to it. Happy hacking. Krishnakant.

Java was well marketed and the time when it came out with libraries like swing, there was no popularly known alternative. As a matter of fact I don't really go by popularity with technologies, specially when it comes to programming languages. Just show me 2 or 3 big apps or web sites which are scalable and take multiple requests. show me just 2 instances where heavy number crunching is done efficiently and I am convinced. I don't care how many apps are developed using java as long as they remain heavy and slw. google runs on python and so do many other big applications. marketing is more about exaggeration, which Sun did for Java.
