How to stop scraping empty pages in category?

Question

I am trying to scrape content from 4 category.Yes,the scraping for 4 of the category worked.The thing is I want to prevent non-existing pages to be scrape but my code below does not work. The reason for the range for loop to be 15 is because my fnb pages got 14.

fnb: 14 pages

services: 1 page

electronic: 2 pages

fashion: 4 pages

---

from bs4 import BeautifulSoup
import requests

def parse():

    cate=["Services","Food & Beverage","Fashion & Accessories","Electronics & Technology"]
    url = "https://www.jurongpoint.com.sg/store-directory"

    for cat in cate:
        for page in range(1, 15):
            
                print(f'Scraping category {cat} page {page}')
                payload = {
                    'level': '',
                    'cate': cat,
                    'page': page
                }
                resp = requests.get(url, params=payload)
                soup = BeautifulSoup(resp.text, 'html.parser')
            

                for link in soup.find_all('div',class_='entry-content'):

                        try:
                            shops=soup.find_all('div',class_="col-9")
                            names=soup.find_all('tr',class_="clickable")

                            for n, k in zip(names, shops):
                                name = n.find_all('td')[1].text.replace(' ','')
                                desc = k.text.replace(' ','')
                                print(name + "\n")
                                print(desc)

                        except AttributeError as e:
                            print(e)

parse()

This is a portion of my output from the code above:

<- Output show scrapping of empty pages

I'm not sure if this is the type of output you are after. However, the following implementation should help you get rid of empty content issues.

from bs4 import BeautifulSoup
import requests

url = "https://www.jurongpoint.com.sg/store-directory"
categories = ["Services","Food & Beverage","Fashion & Accessories","Electronics & Technology"]
payload = {'level': '','cate': '','page': ''}

def parse():
    for cat in categories:
        for page in range(1, 15):
            print(f'Scraping category {cat} page {page}')
            payload['cate'] = cat
            payload['page'] = page
            resp = requests.get(url, params=payload)
            soup = BeautifulSoup(resp.text, 'html.parser')
            if not soup.select("table.table > tbody"): 
                break

            for item in soup.select("table.table > tbody"):
                try:
                    shop = item.select_one("div.col-9").get_text(strip=True)
                except AttributeError: shop = ""
                try:
                    name = item.select_one("tr.clickable > td:nth-of-type(2)").get_text(strip=True)
                except AttributeError: name = ""
                print(shop,name)


if __name__ == '__main__':
    parse()

Answer 2

Note : Number of pages can also increase and you will loose results - So wouldn't it be easy to use the approach already answered https://stackoverflow.com/a/75200178/14460824 to avoid the static range values in general? Just add the scraping part that extracts the necessary parts.

Example

from bs4 import BeautifulSoup
import requests

data = []

def parse(c):
    url = f'https://www.jurongpoint.com.sg/store-directory/?level=&cate={requests.utils.quote(c)}'
    while True:
        soup = BeautifulSoup(requests.get(url).text)

        for e in soup.select('tbody:not([id])'):

            data.append({
                'name':list(e.stripped_strings)[0],
                'desc':e.find_next_sibling('tbody').get_text(strip=True)
            })
        next_button = soup.select_one('.PagedList-skipToNext a')
        if next_button:
            url = next_button.get('href')
        else:
            break
    return

for c in ["Services","Food & Beverage","Fashion & Accessories","Electronics & Technology"]:
    parse(c)

data
