selenium prints weird things...

[snippsat]

You could run code that i have posted or add this to your code that run Selenium.

import sys

print(sys.executable)

Output:
C:\python37\python.exe

This will give the root to the Python interpreter that is used.
Then the changes for me should be done here.
C:\python37\Lib\site-packages\selenium\webdriver\common\service.py

If i had used virtual environment,Anaconda,ect... it would have point to a other Python interpreter,
the i would have needed to make changes there.

Then as posted open service.py and add creationflags=CREATE_NO_WINDOW and save.
Run code again and see if DevTools listening is gone.
