I am inquiring about executing javascript in the browser with selenium. I've seen plenty of ways how to do this, however, saving the output to a variable seems to be something else.

r = driver.execute_script("`; ${document.cookie}`.split(`; bearer_token=`).pop().split(';').shift()")

This makes R = None, which is not the output of the code.

You have to add the return statement:

r = driver.execute_script("return 2+2")
print(r)

will print 4.

And it will print None without return.

execute_script() function in the selenium works for executing something particularly in the specific browser tab only, I am sure that the outputs won't be stored in a python variable. Instead I recommend to save the cookies in your local dir and later perform your tasks.
