cascade
Several times I've been faced with the problem: Get a value from a dictionary. If the key is not present, then get from another key. Normally, the implementation would go like this: if dict.has_key(key1): return dict[key1] elif dict.has_key(key2): return dict[key2]

The other day I've been confronted with a strange situation: I forgot the admin password for a django application. I was playing with installing my own pypi repository, I've configured and deployed a test application and, after a couple of weeks, I forgot the password. I

TL;DR: Install win32 extensions (e.g. using this to put it in your virtual env). Read some code below (there are folders with stuff, messages have CapitalizedPropertyNames). Profit. The other day I needed to perform some statistics on an Outlook mailbox. In particular, use the frequency per day to

One of the projects I worked on was to import a large number of XML files in a PostgreSQL database (as XML files). I chose python to do it. Here are the steps: Database The data source is the SCOPUS database which has a silly number of entries (approx 20,

A while ago I wanted to send a bunch of emails to building companies in order to get some quotes and/or information. Unfortunately, the website in question (pagesdor.be) doesn't provide emails in clear text to allow me copy/paste. Instead it uses a Rotating cypher algorithm

A while ago I got fed up with CSS and its cumbersomeness. As my poison of choice is python, I was thinking it would be quite useful to have a bunch of classes capable of generating CSS automatically in python. One could have a base class, a set of properties,

TL;DR: This post is about an experience I had in 2004 and it’s part of my consolidating technical posts I wrote in time. It may or may not be relevant to today’s technologies. For the last while I was poking around with the glorious D-BUS... As it&

A while ago I had a problem to solve: Write a program to guess a number between 1 and 1,000,000 in python. This is a simple learning program, done in high school or university, particularly when learning a programming language. The Problem The problem can be translated in
copy_expert
My task is to create a script to load a bunch of files into a DB model. The files are CSV, with quoted strings and headers. Postgres has a COPY command which I find fabulous for loading data. unfortunately, the psycopg implementations copy_from() , copy_to() and copy_expert() have

In the programs I write these days I use timing methods to profile the code, mainly because I find it easier to split and sum deltas based on functions. For example, I have a script that loads an XML file, parses it into a relational-ish layout, and uploads the layout

One of the things I did was to write a script to insert records in a PostgreSQL database. The records have with a quite simple structure: * id - char(20) * content - XML field * aside - XML field I was working with a sample of 10,000 entries out of

Sometimes you'd need to show a purely informational page as part of a FormWizard. As far as I could see, there are two solutions to the problem: 1. If the info is something like a summary, you have it available in the "success" page (the one
