>>> driver.execute_script("window.open('');")This actually did switch focus to the new window it created. Thank you again metulburr! :)
That one line was all I needed.
Edit: I realized what you meant by the driver itself switching tab focus. I created a list of window handles and told the driver to go to the last element in the list as this was the most recently opened tab. Like diz:
>>> driver.execute_script("window.open('');") >>> Window_List = driver.window_handles >>> driver.switch_to_window(Window_List[-1])
