If you have followed this blog for a while, you may remember that we’ve covered several XML parsing libraries that are included with Python. In this article, we’ll be continuing that series by taking a quick look at the ElementTree library. You will learn how to create an XML file, edit XML and parse the […]

Today we’ll spend some time looking at three different ways to make Python submit a web form. In this case, we will be doing a web search with duckduckgo.com searching on the term “python” and saving the result as an HTML file. We will use Python’s included urllib modules and two 3rd party packages: requests

Downloading files from the internet is something that almost every programmer will have to do at some point. Python provides several ways to do just that in its standard library. Probably the most popular way to download a file is over HTTP using the urllib or urllib2 module. Python also comes with ftplib for FTP

A couple years ago I started a series of articles on XML parsing. I covered lxml’s etree and Python’s included minidom XML parsing library. For whatever reason I didn’t notice lxml’s objectify sub-package, but I saw it recently and decided I should check it out. To my mind, the objectify module seems to be even

I have read about web2py on several occasions, but never used it myself. Then a few weeks ago, a representative from Packt Publishing contacted me about reviewing their new cookbook about web2py. It’s written by seven authors, namely: Richard Gordon, Pablo Martin Mulone, Mariano Reingart, Bruno Cezar Rocha, Massimo Di Pierro, Michele Comitini and Jonathan

An appropriate alternate title would be: How to control a web page or test your website with Python. Recently, I was given the following assignment: 1) Login to a website 2) click on a toolbar and load a specific search form 3) enter some data into one of the fields on the form and search

Last Thursday (the 5th) I attended Pyowa, the local Iowa Python Users group I founded a few years ago. We had Scott Peterson from Principal Financial Group come and talk to us about Library Gadget, a cool Django-based website he created to track what library books his family has checked out. Now he has lots

TurboGears is one of several web frameworks for Python that are available. The most popular by far is Django. Where I work, we chose TurboGears because of its integration with SQLAlchemy which supports composite keys. At that time, Django did not support that feature and I am not sure if it does yet. Anyway, I

I thought it might be fun (and self-motivating) to create a weekly or bi-weekly series on interesting Python / Tech news items. I realize this is pretty unoriginal, but I like the idea of creating a regular “column” and I’m hoping it will help me stay in the writing groove. Ned Batchelderr does this sort

Last time, we looked at one of Python’s built-in XML parsers. In this article, we will look at the fun third-party package, lxml from codespeak. It uses the ElementTree API, among other things. The lxml package has XPath and XSLT support, includes an API for SAX and a C-level API for compatibility with C/Pyrex modules.

Earlier this year, I was tasked with creating an application that would download information from our organization’s website using Python. The tricky part was that it would be encrypted, gzipped and the payload would be JSON. Could Python do all that? Well, that’s what I wanted to find out. Now it’s time for you to
