Create URL of search result pages from Redfin. For instance — https://www.redfin.com/zipcode/02126

Here is the screenshot of a few data fields that we would be scraping from Redfin

Just go through the guide for installing Python 3 with Linux at

http://docs.python-guide.org/en/latest/starting/install3/linux/

The Mac users may follow the guide at — http://docs.python-guide.org/en/latest/starting/install3/osx/

For the data scraping tutorial with Python 3 set up, we would require some packages to download as well as parse the HTML. Here are different package necessities:

PIP for installing the given packages in the Python at ( https://pip.pypa.io/en/stable/installing/)

Python LXML to parse HTML Tree Structure through Xpaths (Discover how to install it there at http://lxml.de/installation.html)

Python Requests for making requests as well as downloading HTML content for different pages at ( http://docs.python-requests.org/en/master/user/install/).

We require to initially construct search results pages URL. We’ll need to make the URL manually for scraping results from the page. For instance, this is for Boston at https://www.redfin.com/zipcode/02126.

Suppose a script is given the name, Redfin.py. Whenever you type this script name within the terminal or command prompt using a -h

usage: Redfin.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

Then you need to run a Redfin scraper with Python having arguments for sort and zip code. A sort argument is having the options ‘cheapest’ and ‘newest’ listings accessible. For instance, to get the listing of the latest properties for sale within Boston, we might run a script like:

python3 Redfin.py 02126 newest

It will make the CSV file named properties-02126.csv, which would be in a similar folder like a script. Just go through these sample data scraped from Redfin.com for above command.

This Redfin data scraper will extract property listing for the majority of zip codes given.
