Selenium can't find a CSS selector - python-3.x

Question

Selenium catches a NoSuchElementException after retrieving exactly 9 entries from the website. I think the problem might be in that the page contents doesn't have enough time to load, but I'm not sure.
I've written the code following this YouTube tutorial (nineteenths minute).
import requests
import json
import re
from bs4 import BeautifulSoup
from selenium import webdriver
import time
driver = webdriver.Chrome()
URL = 'https://www.alibaba.com//trade/search?fsb=y&IndexArea=product_en&CatId=&SearchText=white+hoodie'
time.sleep(1)
driver.get(URL)
driver.execute_script('window.scrollTo(0, document.body.scrollHeight)')
time.sleep(2)
driver.execute_script('window.scrollTo(0, document.body.scrollHeight)')
time.sleep(2)
items = driver.find_elements_by_css_selector('.J-offer-wrapper')
num = 1
for i in items:
print(num)
product_name = i.find_element_by_css_selector('h4').text
price = i.find_element_by_css_selector('.elements-offer-price-normal').text
time.sleep(0.5)
num += 1
print(price, product_name)
#driver.close()
If you have a clue why Selenium stops at the 10th entry and how to overcome this issue, please, share.

Answer 1

You are getting that because the 10th item is not like the rest. It's an ad thingy and not a hoodie as you've searched for. I suspect you'd want to exclude this so you are left only with the results you are actually interested in.
All you need to do is change the way you identify items (this just one of the options):
items = driver.find_elements_by_css_selector('.img-switcher-parent')

Answer 2

You need to update for the error handling as below:
for i in items:
print(num)
try:
product_name = i.find_element_by_css_selector('h4').text
except:
product_name=''
try:
price = i.find_element_by_css_selector('.elements-offer-pricenormal').text
except:
price=''
time.sleep(0.5)
num += 1
print(price, product_name)
