        library.input_password("//input[@aria-label='Search']", "playwright")
        sleep(5)
    finally:
        library.close_all_browsers()
    print("Done.")

That looks good, although I'd avoid the black-magick of 'previous_level' in locals() (and check for previous_level against None if the call of set_log_level() will return just strings).

Any intention to open a PR with the change solving this issue?
