wxPython: How to Programmatically Change wx.Notebook Pages

Python, wxPython / Mike / July 18, 2012 / wxPython

Occasionally I’ll see someone on the wxPython users group ask about how to make the wx.Notebook change pages (or tabs) programmatically. So I decided it was about time I figured it out. Here is some code that works for me: import random import wx ######################################################################## class TabPanel(wx.Panel): #———————————————————————- def __init__(self, parent, page): “””””” wx.Panel.__init__(self, parent=parent) […]

Getting Started with virtualenv

3 Comments / Cross-Platform, Python / Mike / July 17, 2012 / Python

Virtual environments can be really handy for testing software. That’s true in programming circles too. Ian Bicking created the virtualenv project, which is a tool for creating isolated Python environments. You can use these environments to test out new versions of your software, new versions of packages you depend on or just as a sandbox

Pip Installs Python or pip is a tool for installing and managing Python packages, many of which are on the Python Package Index (PyPI). It is a replacement of easy_install. In this article, we’ll spend a little time trying out pip to see how it works and how it might help us in our Python

wxPython: Creating Your Own Cross Platform Process Monitor with psutil

7 Comments / Cross-Platform, Python, wxPython / Mike / July 13, 2012 / wxPython

This week, I came across a fun Python project named psutil on Google Code. It says it works on Linux, Windows, OSX and FreeBSD. What it does is grab all the running processes and gives you information on them and also gives you the ability to terminate them. So I thought it would be fun

Python 101: easy_install or how to create eggs

2 Comments / Packaging, Python / Mike / July 12, 2012 / Python, Python 101

Today we’re going to take a look at the controversial easy_install method of installing Python modules and packages. We will also learn how to create our own *.egg files. You will need to go get the SetupTools package to follow along. This package doesn’t support Python 3.x so if you need that, see pip or

wxPython: How to Create a Generic Wizard

11 Comments / Cross-Platform, Python, wxPython / Mike / July 12, 2012 / wxPython

The other day on StackOverflow I saw someone who was struggling with the Wizard widget from wxPython. The wizard doesn’t allow much customization when it comes to its buttons, so I decided to see how hard it would be to just write my own Wizard. This code is pretty limited, but here’s my first beta

PyPDF2: The New Fork of pyPdf

16 Comments / Python / Mike / July 11, 2012 / PyPDF, Python PDF Series

Today I learned that the pyPDF project is NOT dead, as I had originally thought. In fact, it’s been forked into PyPDF2 (note the slightly different spelling). There’s also a possibility that someone else has taken over the original pyPDF project and is actively working on it. You can follow all that over on reddit

Python 201: Creating Modules and Packages

17 Comments / Python / Mike / July 8, 2012 / Python, Python 101

Creating Python modules is something that most Python programmers do every day. Any time you save a new Python script, you have created a new module. You can import your module into other modules. A package is a collection of modules. The things you import into your scripts from the standard library are modules or

A Quick Intro to pdfrw

7 Comments / Python / Mike / July 7, 2012 / Python PDF Series

I’m always on the lookout for Python PDF libraries and I happened to stumble across pdfrw the other day. It looks like a replacement to pyPDF in that it can read and write PDFs, join PDFs and can use Reportlab for concatenation and watermarking, among other things. The project also appears slightly dead in that

My long time readers may remember me mentioning that I was trying to put my article code into a Mercurial repository on bitbucket. I haven’t been doing a very good job of that lately, but I did decide to release a whole bunch of wxPython example scripts on there. I use them a lot when

A Simple SqlAlchemy 0.7 / 0.8 Tutorial

10 Comments / Python, SqlAlchemy / Mike / July 1, 2012 / SQL, SqlAlchemy, sqlite

A couple years ago I wrote a rather flawed tutorial about SQLAlchemy. I decided it was about time for me to re-do that tutorial from scratch and hopefully do a better job of it this time around. Since I’m a music nut, we’ll be creating a simple database to store album information. A database isn’t

Reportlab: Mixing Fixed Content and Flowables

12 Comments / Python / Mike / June 27, 2012 / Python PDF Series, Reportlab

Recently I needed the ability to use Reportlab’s flowables, but place them in fixed locations. Some of you are probably wondering why I would want to do that. The nice thing about flowables, like the Paragraph, is that they’re easily styled. If I could bold something or center something AND put it in a fixed
