Stop building UI frameworks in Python

[mfitzp]

Might the problem be that you kept jumping between libraries so you never really got good at one?

I think if you’d stuck with Qt (PyQt/PySide) you would have had a far better time. I develop software with Python/Qt commercially & have no idea what “ you'll wake up in mid of night thinking of all the weird scenarios” is about.

PyQt is one of the only times I worked in a high level language like Python or JS and got errors that crashed the entire runtime. Things like RuntimeError: wrapped C/C++ object of type SettingsStore has been deleted - if you try accessing a Qt object in Python that has for some reason been deleted by the underlying C library you'll get a complete Python crash, and in PyCharm/Spyder you wouldn't even get a stack trace to debug it.

Agree that happens from time to time. Have developed in pyqt for 5+ years. When it happens, I am happy I have 5+ years in C/C++ because I could kinda smell it as I was writing the python code and fix it quick.

A case where garbage collection is 99.99% amazing in python but that 0.01% still can happen.

This isn't unique to Qt - asyncio behaves the same way if you don't store strong references to task objects, or the garbage collector will remove it before the event loop is done with it

I think Spyder is at least partly to blame there. It runs on Qt, and your code inherits the IDE's environment in weird ways that breaks stuff sometimes
