First of all, let me just say that Python + PyQt just rocks.
I've been recently learning Python. Just for fun, basically. Additional benefit is that now I have a better understanding on how to cope with Zope/Plone at my work. Anyway, apart from the Zope/Plone stuff the first thing I did in Python was a command-line script that allows creation and handling of .mpk files that I've used in a couple of my games. MPK or MPak is a simple WAD-like format that stores all the game files in a single package file. I had a C++ CLI application that did the job, but it was really a piece of crap..
So I deciced to write a replacement for that app, in Python. The finished script (
mpak.py) is much nicer to use and works better. I wrote it in Linux and it worked as is in Windows too – neat.
Then, I wanted to try GUI stuff and went with PyQt. I had a simple DVD collection management software called MyDVDCollection that I had written in .NET using C#. It worked, but was not too good either. So I began hacking away with PyQt and now I have PyDVDCollection (pretty clever names, huh? ) that I use for maintaining my collection. It has less code and more features than its .NET counterpart. It works in Linux, naturally, and also beautifully in Vista.
As you can probably tell, I'm very impressed with PyQt and the Python language, and I'll be using them in the future as well.
