This project is for web scraping data from property sites, to show information on the price and availability of properties.
Currently the sites included for pulling data from are:
- Poland:
- Domiporta: https://www.domiporta.pl/
- Otodom: https://www.otodom.pl/
- Olx: https://olx.pl/
- Türkiye:
- Hepsiemlak: https://hepsiemlak.com/
- Emlakjet: https://www.emlakjet.com/
- Zingat: https://www.zingat.com/
To install the project, first clone the Github repository, as described here. Next, install the project by running the following in a bash terminal from the top-level of the project:
pip3 install .The following examples show how to pull data from the different listing sites. There is a class for each listing site. For each one, the pull_listings method can be used to pull the listings. This has the same parameters for each class:
-
data_write_path: string (required). Location and filename (CSV) to save the data to. This is required becuase the data is saved for each page of listings, so that there is data saved even if the program stops running before finishing. -
listing_page_slug: string (required). The string to add to the root URL to get the listings page URL. -
get_listing_previous: boolean (default=True). If True, information will be extracted from the listing preview information on the listings page. -
get_listing_pages: boolean (default=True). If True, each single listing page will be requested and information will be extracted from it. -
page_start: int (default=1). The page number to start at. -
page_end: int or None (default=None). Number of pages to pull. If None, all pages will be pulled.
The pull_listings method will pull the listing data, and runs minimal data cleaning in order to be as fast as possible and avoid errors. The process_data method can be run on the saved raw data to process the data, including converting columns to number format, converting date formats, and tidying and cleaning the data.

To add a new listing site, create a new folder under property_data_scraper, add the module file with the new class, and update the __init__.py files to import the new class. We suggest using an existing class as a template: set the variables (root_url, page_param, data_columns), and define the following methods:
get_listings_list: Get a list of the listings from the listings page soup.get_listing_url: Get the URL of the single listing page from an individual listing in the listings list.get_listing_preview_data: Extract information from the soup of the listing preview (the information about a single listing on the listings page). Return the information as a dict.get_listing_details: Extract information from the individual listing page. Return the information as a dict.process_data: Process the raw data, e.g. convert prices to numbers, convert date formats, convert areas to numbers, convert rooms to numbers, and format and tidy columns.
