I wrote a simple zoopla real estate scraper for just practicing what i learned so far in python,requests,BeautifulSoup overall web scraping fundamentals and by looking at my code i feel like there would be a better and elegant way to write it but unfortunately as a beginner i don't know yet.So, i believe i should let experienced guys here at SO to review my code for enhancement.

import requests
import json
import csv
import time
from bs4 import BeautifulSoup as bs

class ZooplaScraper:

    results = []

def fetch(self, url):
    print(f'HTTP GET request to URL: {url}', end='')
    res = requests.get(url)
    print(f' | Status code: {res.status_code}')

    return res

def parse(self, html):
    content = bs(html, 'html.parser')
    content_array = content.select('script[id="__NEXT_DATA__"]')
    content_dict = json.loads(content_array[0].string)
    content_details = content_dict['props']['initialProps']['pageProps']['regularListingsFormatted']

    for listing in content_details:
        self.results.append ({
            'listing_id': listing['listingId'],
            'name_title': listing['title'],
            'names': listing['branch']['name'],
            'addresses': listing['address'],
            'agent': 'https://zoopla.co.uk' + listing['branch']['branchDetailsUri'],
            'phone_no': listing['branch']['phone'],
            'picture': listing['image']['src'],
            'prices': listing['price'],
            'Listed_on': listing['publishedOn'],
            'listing_detail_link': 'https://zoopla.co.uk' + listing['listingUris']['detail']


        })

def to_csv(self):
    
    with open('zoopla.csv', 'w') as csv_file:
        writer = csv.DictWriter(csv_file, fieldnames=self.results[0].keys())
        writer.writeheader()

        for row in self.results:
            writer.writerow(row)

        print('Stored results to "zoopla.csv"')

def run(self):

    for page in range(1, 5):
        url = 'https://www.zoopla.co.uk/for-sale/property/london/?page_size=25&q=London&radius=0&results_sort=newest_listings&pn='
        url += str(page)
        res = self.fetch(url)
        self.parse(res.text)
        time.sleep(2)
    self.to_csv()

  if __name__ == '__main__':
     scraper = ZooplaScraper()
     scraper.run()

Basically in this scraper i mostly did is json parsing.Problem was all the data on the website was coming from javascript under the script tag so i have to select that tag and then pass it to json.loads() and parse the json dict to find the right key value pair.
