The team development comes with this intro:
PyQtWebEngine is a set of Python bindings for The Qt Company’s Qt WebEngine framework. The framework provides the ability to embed web content in applications and is based on the Chrome browser. The bindings sit on top of PyQt5 and are implemented as three separate modules corresponding to the different libraries that make up the framework.
I used my python version: Python 3.8.3rc1 (tags/v3.8.3rc1:802eb67, Apr 29 2020, 21:39:14) [MSC v.1924 64 bit (AMD64)] on win32
... and PyQt5 version PyQt version: 5.15.0:
>>> from PyQt5.Qt import PYQT_VERSION_STR
>>> print("PyQt version:", PYQT_VERSION_STR)
PyQt version: 5.15.0pip3 install PyQtWebEngine --user
