ANN: KeepNote 0.5.1 - Note taking and organization
by rasmus 29 Jan '09

29 Jan '09

KeepNote is a simple cross-platform note taking program implemented in Python. I have been using it for my research and class notes, but it should be applicable to many note taking situations. KeepNote is ideal for storing your class notes, TODO lists, research notes, journal entries, paper outlines, etc in a simple notebook hierarchy with rich-text formatting, images, and more. Using full-text search, you can retrieve any note for later reference. KeepNote is designed to be cross-platform (runs on Windows, Linux, and MacOS X, implemented in Python and PyGTK) and stores your notes in simple and easy to manipulate file formats (HTML and XML). Archiving and transferring your notes is as easy as zipping or copying a folder. KeepNote is licensed under GPL. KeepNote 0.5.1 has the following features: * Rich-text formatting * Bullet point lists * Colored font * Inline images * hyperlinks * Hierarchical organization for notes * Full-text search * Integrated screenshot * Extension framework * Spell checking (via gtkspell) * Auto-saving * Built-in backup and restore (archive to zip files) * Cross-platform (Linux, Windows, MacOS X) Web site and download: http://rasm.ods.org/keepnote Documentation: http://rasm.ods.org/keepnote/manual.shtml Matt Rasmussen

Tutorial on working with Excel files in Python (without COM and cross platform!) at PyConUS 2009
by Chris Withers 28 Jan '09

28 Jan '09

Hi All, Too many people in the Python community think the only way to work with Excel files in Python is using COM on Windows. To try and correct this, I'm giving a tutorial at this year's PyCon in Chicago on Wednesday, 25th March that will cover working with Excel files in Python using the pure-python libraries xlrd, xlwt and xlutils. I'll be looking to cover: - Reading Excel Files Including formatting, unicode dates and formulae. - Writing Excel Files Including formatting with easyxf and things like freeze pains, print areas, etc - Filtering Excel Files A run through on the structure of xlutils.filter and some examples to show you how it works. - Workshop for your problems I'm hoping anyone who attends will get a lot out of this! If you're planning on attending and have a particular problem you'd like to work on in this part of the tutorial, please drop me an email and I'll try and make sure I come prepared! All you need for the tutorial is a working knowledge of Excel and Python, with a laptop as an added benefit, and to be at PyCon this year: http://us.pycon.org I look forward to seeing you all there!

"Intro to to Scientific Computing with Python" Training Feb 16-20 Austin, TX
by kammeyer 28 Jan '09

28 Jan '09

Hi All, Enthought will be hosting our "Introduction to Scientific Computing with Python class on February 16-20 here in Austin, Texas. The class is specifically oriented toward scientists and engineers who want to learn about all of the tools and techniques available in Python, and in the Enthought Python Distribution specifically. The class has a practical, data processing focus, but will also cover more advanced topics such as easily building graphical user interfaces and making interactive plots. We expect that participants will have experience programming, but no prior Python experience is required. The course is highly interactive, and participants will alternate between learning new techniques, and then immediately applying them in exercises. Therefore, a laptop computer is a must. The course lasts five days, and takes you from the basics of the Python language, all the way to building interactive plotting applications. The schedule is as follows: Day 1: Introduction to the Python Language Day 2: Array Calculations with NumPy Day 3: Numeric Algorithms with SciPy Day 4: Interfacing Python with Other Languages Day 5: Interactive 2D Visualization with Chaco Tuition is $2500. For more information on the course, or to register, visit http://www.enthought.com/training/intro_to_sci_comp.php or call Leah Jones at 512.536.1057. Don't hesitate to call, or email info(a)enthought.com with any questions.
