Just to note, there are official [1] Python bindings available for Qt and this can usually be installed with `pip install pyside2` . [1] https://www.qt.io/qt-for-python

PySide2 is now out of beta?

Yes, it's called "Qt for Python" now

I like the tutorial, but I don't know why you would use PyQt these days. Tkinter is more permissive and has wrappers like appJar which make it disgustingly easy to put together a quick, ugly GUI. If you're building a desktop app that needs to really look good and be fast, why are you using Python?

Why not use python? It’s fast enough for most uses, and with PyQT it looks good enough on top of that it solves most cases rather fast. Sure I can make a solution that runs faster with a smaller memory footprint in Cpp, but my client doesn’t gain any value from me deciding to delay delivery to hit functional requirements they didn’t ask for and don’t need.

I suppose if you are familiar with Tkinter and are happy with how it looks have at it! But there are a ton of things that can be leveraged from Python and Qt separately going this route.

PyQt uses compiled Qt C++ code so isn't really that slow, comparable to how NumPy does it's number crunching. Even if you do find it is slow, you can always come back and branch down to the C++ level when needed, although there are ton of steps you could take to optimize in Python first. There are also all the Qt tools from UI editor and Designer to QML and way more if you really wanna go down the rabbit hole...

What are you suggesting as a really good looking and fast cross platform alternative??

In my research [1] [2] [3], Tkinter was said to be better for basic applications, PyQt better for more advanced projects.

What would you use for an app that needs to look really good and be fast?

Really good? Platform-native APIs.

I think the better appearance of Qt cross-platform is the main drawing point (at least it would be for me). If I were to make a cross-platform application, or even just a Linux one, I'd likely use Qt (with Python bindings because that's what I know). I tried using Tkinter on Linux for a simple utility, but I could not figure out the theming or find any matching themes for Ubuntu.
