To select only the latest value with Selenium

[codessu]

from selenium import webdriver
import time

path = "C:\chromed\chromedriver.exe"
driver = webdriver.Chrome(path) #chromedriver path
'''
First POST  URL
'''
driver.get("https://forums.pcgamer.com/forums/general-gaming.33/?prefix_id=1") # url
time.sleep(0.5)

posturl = driver.find_element_by_xpath("//*[@id=\"js-XFUniqueId11\"]") #list post
posturl.click()
time.sleep(0.5)

'''
UPDATA post URL Comparisons
'''
#time.sleep(1)

The first publishing URL (TXT file) storage update compares the new post to the URL of the TXT file and restarts if the URL is the same as the URL. Run if URLs are different.

I'm planning a program like this, but I don't know how.
It's python's first time, so I searched for things I didn't know, but I couldn't find what I wanted. Please help me a little.
