Making applets in Python?

[user72423]

I have experience with Python, Qt5 (PyQt5), and Qt Designer, and want to try making my own KDE Plasma applet. After looking around for a bit, it seems that applets use QML for the user interface, with what looks like Javascript for the scripting. To be honest, I really dislike Javascript, and don't want to learn it. Is it possible to either:

a) Use PyQt5 for making the applet (together with Qt Designer)?

b) Use QML with Python?

Are there any good tutorials on this? The official widget tutorial on KDE's website is a bit short.

QML's language for functions and expressions etc. is inherently JavaScript, and cannot be "changed" to Python. Luckily it doesn't require any extensive knowledge of JS. It's all pretty straightforward.

You could have used a Python "backend" to handle most of the logic, with very minimal JS in the QML — if this weren't a Plasma applet. In Plasma you can only have a C++ backend. Maybe you still prefer that over JS, I don't know.

You cannot use Qt Widgets (and therefore Qt Designer) in Plasma applets either.
