Extracting information from same page popup in python Selenium webscraping - selenium

Question

Note : I'm experienced in python however just starting out in selenium and webscraping. Please excuse if this is a bad question or if my fundamentals in selenium seem amiss. I could not find an answer in hours of searching hence i ask here
Goal: To extract the "About the Business" information found in Yelp pages of businesses
Some pages have their about the business information within a Read More button based popup (eg : https://www.yelp.com/biz/and-pizza-bethesda-bethesda)
Some pages do not have their business information in a Read More button based popup (eg : https://www.yelp.com/biz/pneuma-fashions-upper-marlboro-3 )
Problem: Unable to navigate to the About the Business popup that appears after clicking the Read More button and extract the text present in it.
Attempts as of now: From googling I had found explanations on how to handle alert popups or window popups. However the code doesnt work. The popup that emerges when clicking Read More button does not cause change in window_handles
import re
# getting all sections of the page
result=driver.find_elements_by_tag_name("section")
About = None
for sec in result:
if sec.text.startswith("About the Business"):
# this pertains only to the About the business section
main_page=driver.current_window_handle
print(main_page) # Returns the current handle
sec.find_element_by_tag_name("button").click()
popup=None
for handle in driver.window_handles: # is an iterable with only one handle
# The only handle present is the main_page handle
print(handle)
if handle!=main_page:
popup = handle
print(popup) # returns None
driver.switch_to.window(popup) # Throws error because popup=None
# THE FOLLOWING SECTION IS NOT EXECUTED BECAUSE OF THE ERROR ABOVE
#////////////////////////////////////////////////////
button_contents=driver.find_elements_by_tag_name("p")
for b in button_contents:
print(b.text) # intended to print text contents
close=driver.find_element_by_tag_name("button")
close.click()
driver.switch_to.window(main_page)
Please help
Thank you to everyone who reads this question and provides advice and answers

Answer 1

That is a custom pop-up so you won't need to switch to it. I suggest to study about getting relative xpath . Use loop to navigate to your urls and include below code
driver.get(your_URL)
readMoreBtnXpath= "//h4[text()='About the Business']/ancestor::section//button"
aboutTheBusinessSec = "//h4[text()='About the Business']/ancestor::section"
fromTheBusinessSec = "((//h2[text()='From the business']/parent::div/following-sibling::div//div)[5]/div)[last()]/preceding-sibling::div"
try:
driver.find_element(By.XPATH, readMoreBtnXpath).click()
button_contents = driver.find_elements(By.XPATH, fromTheBusinessSec)
for b in button_contents:
print(b.text)
except:
print(driver.find_element(By.XPATH, aboutTheBusinessSec).text)

Answer 2

One thing that u should know is that the pop-up is not displayed in a new window. It is instead displayed in the same page itself. Here is the complete code to extract the text from the pop-up:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://www.yelp.com/biz/and-pizza-bethesda-bethesda')
try:
driver.find_element_by_xpath('//*[#id="wrap"]/div[3]/div/div[4]/div/div/div[2]/div/div/div[1]/div/div[1]/section[5]/div[2]/button').click()
p1 = driver.find_element_by_xpath('//*[#id="modal-portal-container"]/div[2]/div/div/div/div[2]/div/div[2]/div/div[2]/div/div/div[1]/p').text
p2 = driver.find_element_by_xpath('//*[#id="modal-portal-container"]/div[2]/div/div/div/div[2]/div/div[2]/div/div[2]/div/div/div[2]/p[2]').text
print("Specialties --",p1)
print("History --",p2)
except:
print('Read more button not found')
Output:
Specialties -- Award-winning pizza: Named one of Fast Company's "World's Most Innovative Companies" in 2018, third-place in the Washington Post Express's of "Best Fast Casual" in 2018, third place in the Washington City Paper's "Best Gluten-Free Menu" in 2018 and won its "Best Pizza in D.C." in 2017, 11th on TripAdvisor's "Best Fast Casual Restaurants -- United States" in 2018.
History -- Since 2012, we've built pizza shops with an edge to their craft pies, beverages and shop design, created an environment where ALL of our Tribe can thrive, supported our local communities and now we'll text you back, if you want. Started with a pizza shop. Became a culture. That's &pizza.
Edit:
Since this doesn't work with this website, replace the first find_element_by_xpath with:
driver.find_element_by_xpath("//div[#class='lemon--div__373c0__1mboc border-color--default__373c0__3-ifU']/button[.='Read more']").click()
This works for both the websites.
