Python Qt6 : First example on Fedora 34 Linux distro.

Qt for Python is the project that provides the official set of Python bindings (PySide6) that will supercharge your Python applications. While the Qt APIs are world renowned, there are more reasons why you should consider Qt for Python.

I tested with Fedora 34 Linux distro:

[root@desk mythcat]# dnf search PyQt6
Last metadata expiration check: 2:03:10 ago on Tue 06 Jul 2021 08:52:41 PM EEST.
No matches found. 

First stable release for PyQt6 was on Jan 2021 by Riverbank Computing Ltd. under GPL or commercial and can be used with Python 3.

Let's install with pip tool:

[mythcat@desk ~]$ /usr/bin/python3 -m pip install --upgrade pip
...
  WARNING: The scripts pip, pip3 and pip3.9 are installed in '/home/mythcat/.local/bin' which is not on PATH.
  Consider adding this directory to PATH or, if you prefer to suppress this warning, 
  use --no-warn-script-location.
Successfully installed pip-21.1.3
[mythcat@desk ~]$ pip install PyQt6 --user
...

Let's see a simple example with this python package:

import sys
from PyQt6.QtCore import Qt
from PyQt6.QtWidgets import QApplication, QLabel

def main():
    app = QApplication(sys.argv)
    win = QLabel()
    win.resize(640, 498)
    win.setText("Qt is awesome!!!")
    win.show()
    app.exec()

if __name__ == "__main__":
    main()

I tested and run well.
