Selenium xpath behaving differently with python than with ruby

Question

I'm having a strange issue with selenium.

1. This ruby code:

   page.all(:xpath, "//table[3]//tr[last()]//td")
   

   Will get me all the cells of the last row of the third table on a page.

2. This python code:

   driver.find_elements_by_xpath("//table[3]//tr[last()]//td")
   

   Doesn't return anything at all.

Edit: The issue was with the page loading at different speeds. Waiting until the page loaded solved the problem.

Answer 1

The issue was that I was following a page redirect and trying to select elements before they were rendered. This answer solved it.
