[FIXED] Web Scraping-Pairing asscoiated prices including real price (2024)

I am trying to scrape this website https://99petshops.com.au/Search?brandName=Ziwi%20Peak&animalCode=DOG&storeId=89%2F&page=1 and there are couple of prices listed oer there in which I am interested to pair with the real price with each listing in a way that csv headers will look like this:

title, lowest_price, lowest_price_0, lowest_price_1, lowest_price_2, lowest_price_3....title, lowest_price, lowest_price_0, lowest_price_1, lowest_price_2, lowest_price_3....

I am getting all the price data but couldn't make it organized as above so far my code for this is:

This selector gives all the prices:

price_list = [pr.find_all('span', {'class': 'sp-price'}) for pr in soup.find_all('table', {'class': 'tbl-price top-10'})]

I just couldn't figure out how to pair all the prices with each associated listing.

Please can anyone help me out here? Thanks in advance!


If I understand you right, you want to get title, price and get the prices from the table when you expand the other prices. I recommend to use pandas for creating the dataframe and saving the CSV:

import requestsimport pandas as pdfrom bs4 import BeautifulSoupurl = "https://99petshops.com.au/Search?brandName=Ziwi%20Peak&animalCode=DOG&storeId=89%2F&page=1"soup = BeautifulSoup(requests.get(url).content, "html.parser")all_info = []for item in soup.select(".pd-info"): title = item.h2.get_text(strip=True) price = item.select_one('span:-soup-contains("Price")').span.text d = {"Title": title, "Price": price} for i, p in enumerate(item.select(".sp-price"), 1): d[f"price_{i:>02}"] = p.get_text(strip=True) all_info.append(d)df = pd.DataFrame(all_info).fillna("")print(df)df.to_csv("data.csv", index=False)

Prints:

 Title Price price_01 price_02 price_03 price_04 price_05 price_06 price_07 price_08 price_09 price_10 price_11 price_12 price_13 price_14 price_15 price_16 price_17 price_18 price_19 price_20
