This article will be about a topic that can be used across platforms, such as Linux, Windows and Mac.
I wrote an article on this topic several years ago, but I think it is time for me to revisit it. Why? Well, lately I’ve been doing a lot of work on a program for sending emails and I’ve been looking at my old article and thinking I missed a few things when I first […]

If you have followed this blog for a while, you may remember that we’ve covered several XML parsing libraries that are included with Python. In this article, we’ll be continuing that series by taking a quick look at the ElementTree library. You will learn how to create an XML file, edit XML and parse the

When I was a kid, I was really into secret codes and ciphers. I thought they were all kinds of fun. My mom thought it would be fun to use some of the ciphers I was so enamored with in treasure hunts for special occasions, like birthdays. She would take something like a Cryptograph Wheel

The PySide GUI toolkit for Python has several standard dialogs and message boxes that you can use as-is. You can also create custom dialogs, but we’ll be saving that for a future article. In this post, we will cover the following dialogs: Color Dialog File Dialog Font Dialog Input Dialog Print & Print Preview Dialogs

As I learn PyQt and PySide, I am writing some tutorials to help my fellow travelers. Today we’ll be looking at how to connect multiple widgets to the same slot. In other words, we’ll be binding the widgets signals (basically events) to slots (i.e. callables like functions, methods) which are better known as “event handlers”.

I am currently reading through Mark Summerfield’s book on PyQt, Rapid GUI Programming with Python and Qt and thought it would be fun to take some of the example applications in it and convert them to PySide. So I’ll be creating a series of articles where I’ll show the original PyQt examples from the book

The Reportlab library is a great way to generate PDFs in Python. Recently, I noticed that it has the ability to do barcodes. I had heard about it being able to generate QR codes, but I hadn’t really dug under the covers to see what else it could do. In this tutorial, we’ll take a

This week, I needed to figure out how to attach an event handler that would fire when I double-clicked an item (i.e. row) in an ObjectListView widget that was in LC_REPORT mode. For some reason, there isn’t an obvious mouse event for that. There is an EVT_LIST_ITEM_RIGHT_CLICK and an EVT_LIST_ITEM_MIDDLE_CLICK, but nothing for LEFT clicks

This week I spent some time learning how to add check boxes to the ObjectListView widget in wxPython. If you don’t know, ObjectListView is a 3rd party wrapper for the wx.ListCtrl widget that makes using the ListCtrl much easier. You can read all about it in this older article from the archives. I had a

Last week I was contacted about a cool sounding book project on Kickstarter: Real Python for Web Development, featuring web2py by Michael Herman. I have to admit that I’m not familiar with Mr. Herman or the person who originally contacted me about the book, but since I enjoy reading Python books and this one sounded

The other day, I was trying to figure out if there was an easy way to grab a class’s defined attributes (AKA “instance variables”). The reason was that we were using the attributes we created to match up with the fields in a file we parse. So basically we read a file line-by-line and each

Python provides robust exception handing baked right into the language. Exception handing is something every programmer will need to learn. It allows the programmer to continue their program or gracefully terminate the application after an exception has occurred. Python uses a try/except/finally convention. We’ll spend some time learning about standard exceptions, how to create a

There are a lot of computer languages that include the ternary (or tertiary) operator, which is basically a one-line conditional expression in Python. If you’re interested, you can read about the various ways it’s rendered in other languages over on Wikipedia. Here we will spend some time looking at several different examples and why you

Some people complained about my last logging article, wondering if it was even necessary since the docs and Doug Hellman have already written on the topic. I sometimes wonder why I write on these topics too, but usually when I do, I get lots of readers. In this case, I’ve gotten almost 10,000 hits just

People keep on asking fun wxPython questions on StackOverflow. Today they wanted to know how to make “flashing text” in wxPython. That’s actually a pretty easy thing to do. Let’s take a look at some simple code: import random import time import wx ######################################################################## class MyPanel(wx.Panel): “””””” #———————————————————————- def __init__(self, parent): “””Constructor””” wx.Panel.__init__(self, parent) self.font
