Question

I am practing to Scrape the websites so I choosed a website https://www.dunzo.com/bangalore/nilgiris-supermarket-koramangala-ejipura

Here is the code that I am using

url="https://www.dunzo.com/bangalore/nilgiris-supermarket-koramangala-ejipura"
r=requests.get(url)
htmlcontnent=r.content 
soup=BeautifulSoup(htmlcontnent,'html.parser')
elem=soup.select('.hozIhp')
print(elem)

Now I am getting output as:

[<p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Britannia Sweet Bread</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Britannia Sweet Bun</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiris Cheese Garlic Bread</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiris Fruit Bread</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiris Pav Bun</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiri's Broken Wheat Bread</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiri's Garlic Bread</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiri's Multi Grain Bread</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiri's Whole Wheat Bread</p>, <p class="sc-1gu8y64-0 dlNpIS sc-1twyv6b-1 hozIhp">Nilgiri's Whole Wheat Brown Bread</p>]

Hence the output came in the form of list. Now I want to extract the item names such as Britannia Sweet Bread, Britannia Sweet Bun, Nilgiris Cheese Garlic Bread etc. I tried some method such as adding.text with soup but it didn't worked. Can someone Please help me how to do that??

Answer 3

The issue you are having; the page is loading dynamically and requests is unable to load the full page

To fix this, you'll need a little more code first, install selenium using pip install selenium download a compactible Google Chrome webdriver from https://chromedriver.chromium.org/downloads (you must have Google chrome installed on your computer) extract the web driver in the same folder as your python script

Then run this code

from bs4 import BeautifulSoup
from selenium import webdriver
import time
 
browser = webdriver.Chrome(executable_path="chromedriver")

url="https://www.dunzo.com/bangalore/nilgiris-supermarket-koramangala-ejipura"
browser.get(url)

#the browser will scroll down for 7 times to load the remaining contents
for i in range (0,6):
    browser.execute_script("window.scrollTo(0, document.body.scrollHeight)")
    #waits for 5 seconds the content to load(You can adjust value depending on your internet speed)
    time.sleep(5)

html = browser.page_source
#r=requests.get(url)
#htmlcontnent=r.content 
soup=BeautifulSoup(html,'html.parser')
elem=soup.select('.hozIhp')
for item in elem:
    print(item.text)
    
browser.close()

output
