We have a bindings header file and an XML file specifying a type system. Which binding generator to choose might be personal preference. However, from a maintenance standpoint, Qt for Python wins his battle. PyQt and Qt for Python both have its advantages and disadvantages. As of the beginning of , the choice between PySide2 and PyQt is not easy to decide. A couple of projects already take advantage of this fact and provide a small abstraction layer over both libraries. The side-by-side comparison of the advantages and disadvantages will make it easier for you to decide which Python binding for Qt to choose.
If you don't want to invest too much in one or the other, you can use one of the present wrappers. Using a wrapper is also my preferred choice for current projects. I want to use Qt Designer to make an application using pyside code. I want to create an executable of the final application, then make an installer for it using InnoDB. Then I want to try and sell it online. If you close the source code of your application which InnoDB does not imply , you need to make sure to provide instructions on how to exchange the Qt library for the customer.
However, this rule may not apply for B2B projects. I don't want to use Qt Designer. I don't know what "dynamically link" vs "static link" actually means or how I would even do that - like physically, what does my brain tell my hands and body to do and where do I go and what do I push to achieve this?? I'm so freaking lost. Do I just need instructions telling people how to install PySide2?
A text file with pip install PySide2? You shouldn't use Python if you need closed source. Even if you freeze your project into a single executable, the scripts will be right there for everyone to read. That's not exactly true, Python bytecode is not very readable - at least it loses all the formatting.
If you really want to make sure nobody can read your source code, you can also compile it using Cython. The same goes for the QML code. But to be honest, most applications these days don't need this level of source code protection since the business logic is somewhere on a server and it's a lot of work to disassemble Python bytecode after all.
You kind of throw all the different namings in a mixer and choose to reference to whatever pops up in your mind. In the Wrappers section it gets even more confusing, what are the wrappers using? PySide2 or PyQt5? The point of this article is to show the differences between the different bindings. So yes, of course, I have to switch between the different names all the time.
Honestly, the most customers of mine use Commercial Version not because of closed-source but because of professional support. Add a comment. Active Oldest Votes.

Just for the record, the OP's question was edited after I made my answer, so most of what I said above has been addressed in the question.
Either that or I did a horrible job of reading the question the first time around. The link to the related thread unfortunately now appears to be broken. This is plain wrong! How often I have to consult screeming customers, who were mis-consulted by such experts. The problem is, they are not allowed to switch from Comunity to Professional license close before release.
Qt requires that the entire development is done in Commercial from the beginning. Your concern in bullet 3: I know that it can be done but I might need to make changes to QT without releasing the code for it This is a very strange requirement. Usually frameworks contains bugs so fixing them might be needed. Not releasing is good because it will mean extra cost you can still get your changes to the original library by commiting them but it will take time till they will be released in the new version Can you send a link for some commercial LGPL Qt program?
True frameworks contain bugs, but usually you just work around them, especially in terms of closed source frameworks. There's not much cost to posting a patch to changes you make to the library either; you only have to distribute it to your customers when they ask.
