Extracting High School Names from Web Data in Python: A Simple Guide

Web scraping can yield a wealth of information, but sometimes you need to sift through the data to find exactly what you need. One common task for those diving into web data parsing with Python is to extract specific information, such as school names from housing listings. In this guide, we'll tackle a frequent challenge: how to extract the high school name from a scraped list of school data. Let's break down the problem and explore some effective solutions.

The Problem

Imagine you have scraped data from a website that details various school information. Your list might look something like this:

Your goal is to retrieve the high school name, which in this case is RIVERSIDE, and store it in a variable. You want the variable to look like this: hs = "RIVERSIDE".

How can you accomplish this in Python? There are a couple of straightforward methods to achieve this: using basic string manipulation or employing regular expressions (regex).

Solution Methods

Method 1: String Manipulation

One of the most intuitive methods to extract the high school name involves basic string manipulation techniques. Here’s how you can achieve this:

Explanation:

Strip and Split: We start by stripping whitespace and then splitting the string by the newline character.

Filtering: We filter out lines that specifically contain “High School”.

Extracting the Name: Once we find the correct line, we split it at the colon (:) to separate the label from the name and clean the name by removing any extra whitespace or newline characters.

Output:

Running the above code will produce:

Explanation:

Importing the re Module: We start by importing Python's regex module.

Defining the Pattern: We compile a regex pattern to find the text “High School” followed by a colon and then the school name.

Searching: We execute the search and extract the second group, which contains the desired high school name.

Output:

The output for this method is also:
