Re: [Tutor] Making pretty web pages from python code examples?
: Basically, I'm trying to read python code examples from files on : disk and generate pretty little web pages from them. I think you may want sphinx [0] which is available in PyPI [1]. It understands reStrucTured text and adds a few Sphinx-specific directives/features for pulling the docstrings from your python modules. Much easier than building your own. Thanks! Looks like just what I'm after. -Modulok- ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] How to deploy and upgrade python and its apps
Hi All, I would like to understand how to deploy specific version of python and its modules and apps in consistent manner. Use case: 1- How to install specific version of python in my own path. (consider NFS, /opt/sw/bin and /opt/sw/lib). This particular share is mounted on all dev machines. 2- How to develop application _using_ only the python and its libs installed in /opt/sw/bin and /opt/sw/lib. 3- Now once developed, my applications is dependent on python and its libs in /opt/sw/bin and /opt/sw/lib. Hence I want to keep it in sync on all machines (ofcourse it is mounted). Giving me chance to rollback it necessary. Here is what I am thinking of doing it. Please correct me and suggest the better way! 1- Install python in this location. ./configure --prefix=/opt/sw make make install 2- setenv PYTHONPATH=/opt/sw/lib/python 3. Add whole /opt/sw to some dvcs (hg) and keep updating to stable revisions. -- Dilip -- Dilip ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] How to deploy and upgrade python and its apps
Hi Dilip, There is some good information about this in the book Expert Python Programming by Tarek Ziade, and maybe you could look into http://pypi.python.org/virtualenv, easy_install and zc.buildout.

[Tutor] Problems with creating XML-documents
I'm having problems with creating XML-documents, because I don't seem to write
it to a document correctly. I have to write the document from a loop:
doc.write('?xml version=1.0 encoding=iso-8859-1?\n')
for instance in query:
if doc != None:
text = str('record id=' + str(instance.id)+ '\n' + \
' date' + str(instance.datetime) + ' /date\n' + \
' order' + instance.order + ' /order\n' + \
'/record\n')
doc.write(text)
When I try to parse it, it keeps giving errors. So I tried to use an external
library jaxml, but I don't know how to implement this in the loop because the
output is written at the end (doc._output) and I overwrite my values. The code
below is from the jaxml website
# an equivalent version using JAXML
import jaxml
doc = jaxml.XML_document()
doc.sometag(someattr=1).anothertag(jaxml=Nice)
doc.thirdone(Yo)
doc._output(sample.xml)
Can anybody point me in the rght direction or is there another library that I
can use to create valid XML-documents?

I am frustrated with the lack of clarity and completeness. Please
respect our time as volunteers by giving complete explicit informaion.
Show us the resultant file.
Tell us what parsing tool you are using.
Show us the exact errors.

Is that because you don't understand XML or because the
output is not what you expect? How is the data being generated?
Are you parsing an existing XML source or creating the XML
from scratch? I'm not sure I understand your problem.
text = str('record id=' + str(instance.id)+ '\n' + \
' date' + str(instance.datetime) + ' /date\n' + \
' order' + instance.order + ' /order\n' + \
'/record\n')
You can simplify this quite a lot. You almost certaionly don;t need
the outer str() and you probably don;t need the \ characters either.
Also it might be easier to use a triple quoted string and format
characters to insert the dasta values.
When I try to parse it, it keeps giving errors.
Why do you need to parse it if you are creating it?
Or is this after you read it back later? I don't understand the
sequence of processing here.
So I tried to use an external library jaxml,
Did you try to use the standard library tools that come with Python,
like elementTree or even sax?
I think we need a few more pointers to the root cause here.

Re: [Tutor] Introduction to modelling with Python
On Wednesday April 7 2010 11:38:07 AG wrote: Eike I just wanted to come back to you on the book recommendation you made Python scripting for computational science - I tracked down a cheapish copy of the 3rd edition from 2009 and flipping through it (it only arrived yesterday), it seems like it is going to be very useful. Certainly it draws a lot on numpy, goes into using Tcl for GUIs, and a number of recipes for scripting, regular expressions and so on ... lots to get my head around. Python scripting for computational science also contains a section about solving differential equations. It is in one of the chapters about additional libraries. The book contains many Fortran examples. As an alternative to Fortran you should also look at Cython. This is a very fast, compiled companion language for Python. It produces *.so (*.dll) files that can be directly loaded into Python as modules. http://www.cython.org/ With respect to my original question then, equipped with this book you recommended, a book on differential equations, and one on an intro to environmental modelling, that should give me enough to work on for the time being. An other possible book for an inter library loan might be Mathematical Models in Biology from Leah Edelstein-Keshet. It contains many differential equations from different fields of biology. Additionally it contains a very good introduction how to write your own partial differential equations. It is not an ideal book for someone who wants to do numerical computations (like you), because the differential equations are solved symbolically with pen and paper. On the other hand: Why do numerical experiments, when you can find all possible solutions at once just with pen and paper. I believe however the real reason is, that the book was written before computers became cheap (1988). So, just wanted to close the circle by letting you know that I took your recommendation, and it looks like it will pay off in time. Great!
