I’ve skipped to a new series of PyQt tutorials. This one was produced by Sentdex. I’m sure the guy must have a name but I’m yet to hear it. Anyway, he’s produced a slew of videos on Python programming and many of them are specifically for PyQt4 programming. He recommends PyQt4 over PyQt5–says it is simpler but I would rather work with 5 and I’m not even sure it’s possible to simultaneously have both 4 and 5 environments. I seem to be having a few problems with that scenario.
Sentdex has a web site called pythonprogramming.net. He also has a $5/month subscription plan that allows you to download the videos, take quizzes, ask questions, etc. I signed up for the subscription plan.
And I’ve just discovered another series of videos for using PyQt and the Qt Designer. Here is one of the videos on You Tube.
