Which one to get the last element?

Question

Python

How to get the last Rating from this table, namely 12448 (it will always be different)
Tried using xpath

tree = html.fromstring(pars.content)
            stata = tree.xpath('//*[@id="bg"]/div[3]/div/div/div/div/div/div/div/div/div/table/tbody/tr[32]/td[3]')
            print(stata)

but not working

<table class="cntr wa mlra">
    <tbody><tr>
      <td class="p5">Место</td>
      <td class="p5">Имя</td>
              <td class="p5">Рейтинг</td>

Answer 1

If only the last rating is needed, is it worth bothering with building and searching in the DOM model. The search is slow, when processing large pages, the memory eats up unmeasured.
It's easier to find a hand-to-hand rating

import requests
. . .
content = requests.get('адрес чего-то') 
texthtm = content.text
substr = '<td class="yell">'
posb = texthtm.rfind(substr) + len(substr)
pose = texthtm.find('</', posb)
rating = int(texthtm[posb : pose])
print(rating)
