I hope you can get something after reading this article. Let's take a look at this "how to use the Python PyQt5 module to achieve a browser" article.

1. The first is the installation of the environment (I use PyCharm,python3.6)

Pip3 install PyQt5 (if no version is specified, the latest one will be installed by default)

Pip3 install sip

Pip3 install PyQtWebEngine

PyQtWebEngine is a set of frameworks for QtWebEngine that provide the ability to embed Web content in applications and are based on Chrome browsers. )

Running result

4. Tips

If you are prompted about which modules are missing, Pycharm will usually be prompted to install them. If you are not prompted, you can refer to the library I ran successfully:
