i have a mysql database that i'd like to query. i would like to format the results a certain way, then turn it into a pdf. in the past, i used PHP and FPDF, while it worked, it was a pain and tedious. i don't think PHP can handle this sort of thing. i don't have much experience in python or ruby but this would be a great project to do in either language so i can get more familiar. it doesn't have to be web based. it can be desktop script that i could run with a cron or manually. hope someone can point me to some resources. thanks.
In Ruby you have a number of options for your PDF authoring, and your DB management is very easy if you use the ActiveRecord library (comes with Rails) or Sequel to read or write data.
Complete and heavy duty PDF authoring can be done using Prawn... it requires some studying, but it's an amazing library.
You can also create HTML web pages and convert them into PDF using the wicked_pdf gem, which is quite simple to use.
Or, you can combine it all, or write simple PDF's with simple tables and text using the combine_pdf, which is as easy as it gets and also allows you to use PDF templates (so you can have a well designed template and just add the text you need).
I love Ruby and I think it's very easy to learn. Plus, it has more applications than just web programming - there's even a project called RubyMotion which lets you program native applications for iOS and Android using Ruby!
I'm sure you'll love Ruby.
In Python, you can use pyPdf to create PDF files. As for the querying a mySQL DB, you can use mySQLdb. Installing it is slightly harder than other modules, but once you have done so, it's just like any other sql package. Hope it helped.

I really am lost.
I've written a python script which takes two files, converts one to the same format as the second and outputs the differences.
I now need to create some kind of GUI?
I'm thinking a relatively simple HTML page which allows users to click on two separate boxes to upload each of the files and then submit them - resulting in the output being offered as file which the user can download to the PC.
Any help of direction would be really appreciated. It's only really a guess that HTML will be my best/simplest choice. Working from the command line isn't really an option I can go with. The PC that this will sit on will not have internet access. I intend to have this installed on the PC as an application.
I accept I'll need to make some changes to my Python code. Posted this here as I'm not sure Python questions would have been the best place but I'll move it if suggested.
Please, any help at all will be useful. First timer
This is not a kind of answer that normally gets a reply on StackOverflow because it is much too broad / subjective.
Given the fact that you are quite new I would like to provide a solution anyway that will allow you to build a GUI quite easily like EasyGUI.
A very easy example:
import easygui
easygui.msgbox('This is a basic message box.', 'Title Goes Here')
Other possibilities (less customizable but arguably easier) are Wooey (automatic web interface generation for your script) and Gooey (automatic GUI generation for your script.
Please, for next time, remember to always provide a Minimal Reproducible Example and read https://stackoverflow.com/help/how-to-ask
I don't suggest you use the Django Framework for such a small application.
You should definitely use Flask for this. Flask is more lightweight

I am installing Cisco ASA Firewall for my customer at several locations. The basic ASA configuration for all the locations is the same with a deviation of certain things like Interface IP addresses, Routing next hops, etc.
For every location I have an excel sheet with all the variables.
I know basic Python. The question is : is it possible to write a script in python which will read the variables in the Excel Sheet and generate the configuration for ASA?
Moreover could someone recommend a source to learn scripting targeted for networking or such an automation task? (Simply googling led me to many confusing options and hence the question here)
I suggest you use templating engine such as jinja2 along with python.
(https://github.com/jedelman8/interop-nyc-2014.git)
(http://keepingitclassless.net/2014/03/network-config-templates-jinja2/)
Or you can use simple Ansible tool along with Jinja2 templates to generate configs. (No need for programming skills)

(https://sreeninet.wordpress.com/2014/09/28/network-device-configuration-using-templates-with-jinja2-and-yaml/)
(http://jedelman.com/home/ansible-for-networking/)
I would also suggest to look at a very good library "netmiko" for ssh connection in future and push, pull config (https://github.com/ktbyers/netmiko/tree/master/examples)
All above options can work for you. See below examples. I am a Network professional myself and found these useful.
This is pretty easily done with Python, but will take a bit of learning.
Depending on the format of the Excel file, I would recommend OpenPyXL, or XLRD.
This will also depend on the configuration format you are wanting to output. If it's a JSON Config file, you can simple use the built-in json module. Otherwise, there are a variety of other modules out there for things like CSV, etc.
One warning, however. If you hard-code all of your Excel columns/positions within your code, you could be in for a world of hurt in the event that the columns change.

What are the best (more or less mature, supporting more advanced logic, having acceptable performance, scalable to some extent) open source Semantic Web libraries and tools (RDF storage, reasoning, rules, queries) for Python nowadays? Historically Python tools (cwm) were among the first to appear, but it still seems that everyone uses Java back-ends for performance and Python as mere client if at all. My purpose is to learn the technology and maybe some future use in production system if it proves itself up to the task. The task is not yet defined, but as I see it its building a knowledge base, linked with some external resources, and customized facet-navigable web front-end.
If some building blocks based on Python are not good enough, then what is the suitable piece from Java/C/C++/whatever world.
Typical stack is also of interest, if there are one or two clear winners.
Thanks.
A survey of of Python libraries and tools for Semantic Web programming is available here. It includes libraries for working with RDF as well as Python-friendly triple stores.
Toby Segaran's book Programming the Semantic Web also has a lot of programming examples in Python.
You could check out the pyswip. It could work with the SWI-Prolog. Wish it would fit for requirement. :)
To name some, check out RDFLib and CubicWeb.

I am really new to Python and I have been looking for an example on how to write a Web Service (XML - SOAP) in Python with Google App Engine with no luck.
Can anyone point me to an article or give me an example on how to do this?
I was curious about this myself and not finding anything I decided to try to get something to work. The short answer is that it turns out a SOAP service can actually be done using the latest alpha ZSI library. However it isn't simple and I didn't do much more than a simple request so it could fall apart with a complex type. I'll try to find time to write a tutorial on how to do it and edit this answer with more detail.
Unless this is a hard requirement I would do what jamtoday says and go with a REST or RPC service. The SOAP way could be filled with trouble.
Update: For anyone interested I've written a tutorial on how to deploy a SOAP service to the Google App Engine. It is long process so I'm just linking to it instead of pasting it all here.
If you want to do something with App Engine specifically, there are libraries that will make it much faster on your end. I'd recommend looking at the XML-RPC and REST examples.
http://appengine-cookbook.appspot.com/recipe/xml-rpc-server-using-google-app-engine/
http://github.com/fczuardi/gae-rest/tree/master
I know this is an old thread but just in case if someone happens to read this.
I have just start an open source project for creating web services on GAE.
Project site: http://code.google.com/p/webserviceservlet/
Hope this is helpful.
EDIT:
Just noticed that this is a python question and the link project is java project....
Here is a Python Web Services project that might be helpful.
EDIT
And here is a SOAP consuming demonstration....
You could take a look at the Bottle framework. It's a Python framework which with you can easily create a REST api.
In my opinion, REST is definitely better than SOAP. It can be easily consumed by any software able to speak http, and it's faster to implement.

I'd like to write a python library to wrap a REST-style API offered by a particular Web service. Does anyone know of any good learning resources for such work, preferably aimed at intermediate Python programmers?
I'd like a good article on the subject, but I'd settle for nice, clear code examples.
CLARIFICATION: What I'm looking to do is write a Python client to interact with a Web service -- something to construct HTTP requests and parse XML/JSON responses, all wrapped up in Python objects.
I can't point you to any article on how to do it, but I think there are a few libraries that can be good models on how to design your own.
PyAws for example. I didn't see the source code so I can't tell you how good it is as code example, but the features and the usage examples in their website should be a useful design model
Universal Feed Parser is not a wrapper for a webservice (it's an RSS parser library), but it's a great example of a design that prioritizes usage flexibility and hiding implementation details. I think you can get very good usage ideas for your wrapper there.
My favorite combination is httplib2 (or pycurl for performance) and simplejson. As REST is more "a way of design" then a real "protocol" there is not really a reusable thing (that I know of). On Ruby you have something like ActiveResource. And to be honest, even that would just expose some tables as a webservice, whereas the power of xml/json is that they are more like "views" that can contain multiple objects optimized for your application. I hope this makes sense :-)
This tutorial page could be a good starting place (but it doesn't contain everything you need).
You should take a look at PyFacebook. This is a python wrapper for the Facebook API, and it's one of the most nicely done API's I have ever used.
You could checkout pythenic jobs, a nice, simple, but well-formed "Python wrapper around the Authentic Jobs ... API" as a good example. That's what I'm doing now :)
