Extracting text from a website using selenium

问题

trying to find a way to extract the book's summary from the good reads page. Have tried Beautiful soup / Selenium, unfortunately to no avail.

link:https://www.goodreads.com/book/show/67896.Tao_Te_Ching?from_search=true&from_srp=true&qid=D19iQu7KWI&rank=1

code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from bs4 import BeautifulSoup
import requests
link='https://www.goodreads.com/book/show/67896.Tao_Te_Ching?from_search=true&from_srp=true&qid=D19iQu7KWI&rank=1'
driver.get(link)
Description=driver.find_element_by_xpath("//div[contains(text(),'TextContainer')]")
#first TextContainer contains the sumary of the book
book_page = requests.get(link)
soup = BeautifulSoup(book_page.text, "html.parser")
print(soup)
Container = soup.find('class', class_='leftContainer')
print(Container)

Error:

container is empty +

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//div[contains(text(),'TextContainer')]"} (Session info: chrome=83.0.4103.116)

You can get the description like so

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
...
driver.get("https://www.goodreads.com/book/show/67896.Tao_Te_Ching?from_search=true&from_srp=true&qid=D19iQu7KWI&rank=1")
description = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.CSS_SELECTOR, 'div#description span[style="display:none"]'))
)
print(description.get_attribute('textContent'))

I have utilised a CSS Selector to get the specific hidden span that contains the full description. I have also used an explicit wait to give the element time to load.
