Draft ‘Starting with Python’ guide in ShowMeDo

For a while I’ve been mulling adding text-only tutorials to ShowMeDo – basically a regular video page sans the video-box. By adding Guides we can write short tutorials which help to connect our video series together and also link to external tutorials.

The first Guide is Starting with Python:

Installing Python
Language overview
Writing your first program
Learn Python [...]

Introduction to Python web-programming: CGI

Web-programming is a pretty big topic. Complex web-apps might require the knowledge of SQL, Javascript, HTML, CSS as well as a language like Python. It can be quite overwhelming. There are many frameworks that will help you handle this complexity (e.g. Django, Turbogears or Pylons), but if you don’t know roughly what [...]

Using pyWin32 with Excel

I’ve started another Club series to show you how to use pyWin32 on Windows to talk to COM-aware applications like Excel.

Personally I’ve used Excel as a simple charting tool for quick science research. I figured that several screencasts on this leading to the creation of a Python COM server would make for a good [...]

Building a wxPython Image Viewer – 8th episode

For the 8th episode in the series we look at Avoiding wx Memory Leaks with .Destroy() to teach some good programming practice.

Using wx.Image & wx.StaticBitmap

Now we actually load and display an Image! We use a wx.Image which reads a graphic image from our hard-drive.

First we show the image’s dimensions in the status-bar using .SetStatusText(…). Next we use the new ShowBitmap(self) function to convert the Image to a wx.StaticBitmap which is shown inside the Panel. We ask the Frame to [...]
