Hello, I get the error during run the code from Listing 13. basic/widgets_1.py (page 38, "Create GUI Applications with Python & Qt6" The hands-on guide to making apps with Python Version 1.0, 2021-04-09).
Traceback (most recent call last):

Hello, @AstroLinux, welcome to the forum!
Try changing Qt.Alignment
to Qt.AlignmentFlag
and it should work.

@AstroLinux this is due to a change in PyQt 6.1 (released 11th May) -- the enum names were updated to bring it in line with PySide6.
PyQt/PySide 1:1 Coaching with Martin Fitzpatrick — Get one on one help with your Python GUI projects. Working together with you I'll identify issues and suggest fixes, from bugs and usability to architecture and maintainability.
It's a good change, as it keeps PyQt/PySide more compatible, but it does mean I need to re-do all the code examples in the book! I'll be releasing an update shortly to fix this.
edit: @AstroLinux @PedanticHacker the updated version of the PyQt6 (for 6.1) has been uploaded now. You can download it from https://account.mfitzp.com (once logged in).
There weren't that many changes in the end, still I may have missed some -- let me know if you spot anything amiss. I wanted to get this out quickly as I've already have 5 emails about it this morning :D
