Selenium python - help

Hello guys, I am stuck in the automated testing in one of the field button organization , my web driver says unable to find element of exceptional error.
my question is

  1. it is dynamic xpath - but i tried but also failed
  2. its like drop down element - i tried but in html page no select as tag input
    3.Switch to alert-i tried because if we entered a string it will popup new window then need to click create, edit and cancel tried but failed

please provide the suitable solution for this
