Find element by value Selenium/Python
You can try to click/select element via displayed text. Pseudo code:
driver.find_element_by_xpath("//option[text()="Some text"]").click()
The problem is with the first xpath. You are trying to locate an input while you need to get option.
Try this:
driver.find_element_by_xpath("//option[@value='T_U0']").click()
