How do I run command from web browser console in python?

I have recently been trying to run a command through python in a web browser, as if using chrome developer tools.

This is easy to do from chrome, but how would I do it from python? I have no idea how I would go about replicating this from a python script. The browser command I am wanting to run is specific to the website I am working with, which is why I need to use the command line.

How can I repsslicate running a command in the browser command line, in python 3? Sorry if this is a stupid question. Thanks!
