Web Scraping Packages
For the data scraping tutorial having Python 3, we would require some packages to download and parse the HTML. Here are the package requirements:
PIP for install these packages in the Python (https://pip.pypa.io/en/stable/installing/)
Use Python Requests for making requests as well as downloading HTML content pages at (http://docs.python-requests.org/en/master/user/install/).
Use Python LXML to parse HTML Tree Structure with Xpaths (Discover how to install it here – http://lxml.de/installation.html)
We need to first make search results pages URL and create the URL manually for scraping results from the page. For instance, go through the one used for Boston- https://www.zillow.com/homes/02126_rb/.
Runa Zillow Scraper
Presume that a script is known as zillow.py. Whenever you type script name in the terminal or command prompt using a -h
usage: zillow.py [-h] zipcode sort positional arguments: zipcode sort available sort orders are : newest : Latest property details cheapest : Properties with cheapest price optional arguments: -h, --help show this help message and exit;
You have to run a Zillow data scraper using Python having arguments for sort and zip code. The sort arguments have the options ‘cheapest’ and ‘newest’ listings accessible. For example, to get listing of the latest properties for sale in the Boston, Massachusetts we will run a script like:
python3 zillow.py 02126 newest
It will make a CSV file named properties-02126.csv, which will be available in the similar folder like the script. Just go through some extracted sample data from Zillow.com for the above command.
The Zillow scraper can extract real estate listings for the majority of zip codes given. If you require some professional assistance with scraping real estate data, just contact us!
