I recently became aware of a Tic-Tac-Toe challenge on github where the programmer is supposed to create a Tic-Tac-Toe game that let’s the player win every time. You have to code it in Python, although the people behind this challenge prefer you do it with Django. I don’t know Django very well, so I decided […]

I recently tried to help someone (on the wxPython mailing list) figure out how to use a Grid widget (wx.grid.Grid) via XRC. It should be simple, but if you run the code below, you’ll discover a weird issue: import wx from wx import xrc ######################################################################## class MyApp(wx.App): def OnInit(self): self.res = xrc.XmlResource(“grid.xrc”) frame = self.res.LoadFrame(None,

In this article we will be taking the code from the previous article on Bottle and changing it such that it uses SQLAlchemy instead of just normal SQLite code. This will require you to download the bottle-sqlalchemy package from PyPI. You can also install it using “pip install bottle-sqlalchemy”, assuming you have pip installed. You

It’s also sometimes called a “micro-framework”, probably because Bottle consists of just one Python file and has no dependencies besides Python itself. I’ve been trying to learn it and I was using the official Todo-list tutorial on their

My wife teaches 3rd grade math and she recently learned about the process of obtaining the digital root of numbers. The digital root is a single digit number found by summing the individual digits. So for 15, you would add 1+5 to get 6. Thus 6 is the digital root of 15. The trainer that

At my job, we sometimes need to write a PDF to memory instead of disk because we need to merge an overlay on to it. By writing to memory, we can speed up the process since we won’t have the extra step of writing the file to disk and than reading it back into memory
