  • Python(x,y): Python as your next MATLAB

    by Vincent Noel

    This training session will introduce the Python scientific stack to Engineers who use matlab in their day-to-day job and want to switch to an open solution or explore other alternatives. The basics of Python will first be presented: syntax, variable types and data structures, functions and flow control, exceptions. Python modules and tools required for matlab-like programmation in Python will be presented: ipython, numpy and matplotlib. Several Python applications typical of engineering problems will be presented and compared with their matlab version, as time will allow: plotting (time series, histograms, pseudocolor plots, etc.), basic I/O (e.g. ASCII, CSV, matlab MAT files), signal processing, mapping, etc. The creation of user interfaces with PyQt will be briefly introduced. Differences between Interactive and non-interactive programming will be described. Along the session, key differences with matlab will be underlined and discussed. Sources of information and documentation, online and offline, will be presented.

    These concepts will be introduced as coding exercises using the Python programming environment provided by the Python(x,y) distribution, which is freely downloadable and includes recent versions of Python, numpy and matplotlib. This session will also focus on using Python(x,y) efficiently for Python programmation. Attendees should bring their own laptop running Windows. It is also recommended that they download and install the pythonxy distribution from http://www.pythonxy.com/.

    Although no knowledge of Python is required to attend this session, a basic knowledge of matlab and of its typical programming usage is needed.

  • New beauty in Camelot

    by Erik Janssens and Jeroen Dierckx

    Camelot is a Python framework that leverages SQLAlchemy and QT to build rich desktop applications. The model - view definition used was inspired by the Django Admin interface. Some see it as a replacement for MS Access, but it's underlying libraries allow much more advanced features.

    In this talk we will focus on the changes and new features that were introduced in Camelot and more importantly, how they can be used in your applications. Those features range from Matplotlib chart integration and new types of actions to displaying custom SQLAlchemy queries in a table view.

    We will share our experiences with large scale deployment of Python and Camelot applications to the desktop of the user. In a number of case studies we will point out the mistakes we made and how they were corrected.

    At 3:30pm to 4:30pm, Wednesday 22nd June
