Why Should You Use Python for Web Scraping
Although there are various tools for web scraping, Python remains an efficient option. With just a few lines of code, you can access and collect data from multiple web pages.
Here are some of the reasons why you should use Python for web scraping
It is easy to use
Python is often considered as a simple programming language. It is less messy and complicated to use and understand. This could be because the language does not require brackets and semi-colons. Therefore, Python’s readability and simplicity make it an ideal choice for web scraping.
In addition, the syntax is easy to understand because reading Python codes is similar to reading a regular sentence in English.
It does not require bulky codes
Another benefit of writing Python web scraping codes is that you get more with less. With a simple code, you can implement the complex process of accessing and retrieving data from web pages.
Libraries
Several libraries make Python web scraping easier and more efficient. In the preceding part of the guide, we have discussed 10 (ten) Python libraries, their features, pros, and cons. Therefore, developers have various options and resources to customize codes to meet their web scraping needs. These libraries also support various web scraping methods, including XPath expression and CSS selectors.
Dynamic coding
Another unique feature of the Python language is it saves time. You don’t have to spend several hours writing long codes or defining datatypes for variables. Instead, you can directly use the variable within the code wherever it is needed.
Active Community
Python has a large, dynamic, and active community. You can join any of the forums on the various social media platforms. So, when you are stuck or need clarification about a concept, all you need to do is ask. You will receive opinions from those who are experts or have once been in that situation.
Versatility
Python is a very versatile language because it has several applications. Since it is often used in artificial intelligence, data science, and machine learning, Python is an ideal choice for web data scraping involving processing and analysis.
In addition, Python can be used to interact with APIs and automate web data retrieval activities, which makes it great for handling large datasets.
The Process of Python Web Scraping
There are two ways to collect data from the internet- using a Python web scraping tool or creating your script. Organizations with frequent data scraping needs may consider creating their own script to customize their Python web scraping activities. This section will provide a step-by-step guide for successful Python web scraping activities.
The steps include:
Select target websites
The first step in Python web scraping is to define your target websites. This involves identifying the kind of information you want to get. However, many websites have anti-scraping measures such as CAPTCHAs, which can detect your Python web scraping activities and ban your IP address. A solution to such challenges is to use Netnut’s industry-level proxies.
In addition, some websites are heavily reliant on JavaScript. Therefore, it may be challenging to use Python web scraping to collect data. As a result, you should know everything you can about the target website to avoid hiccups on your journey to Python web scraping.
Inspect the website
While you may be tempted to go straight to writing codes, inspecting the website is crucial. After you have selected the target website, you MUST review it. Interact with the website like a regular user to get familiar with the interface. Go through the terms and conditions to understand the website. Also, you need to inspect the HTML structure of the web page because this plays a significant role in how it appears.
Most browsers provide tools for inspecting and finding out details about a particular webpage. For example, if you want to collect email and name, you can use an e-commerce website. When you are inspecting the website, you will find a list of emails and corresponding names.
Since Chrome is a popular browser and often used for web scraping, we shall make reference to it. If you want to inspect a website on Chrome, click on the three dots in the top right corner. Select More Tools and then click on Developers Tools. MacOS users can find this option by selecting the menu bar and choosing View > Developer > Developer Tool.
On the Developers Tools page, find the “Elements” tab to explore the content of the website. This page displays the elements, including those with a class or ID name. In addition, it allows you to inspect the DOM (Document Object Model) of a web page.
The HTML code gives an overview of the content of a website created by the developer. On the other hand, the DOM is a dynamic overview of the HTML code generated by the browser.
NB: Take note of these ID names as you need to integrate them in your script for Python web scraping.
Install Python and supporting software
At this stage, you have a good understanding of the website’s HTML structure and class names. Therefore, you are ready to get started with the process of Python web scraping.
Since you need to create a Python script, you need to download and install Python. Be sure to download the latest version (they often come with upgraded features) from Python’s official website.
Another critical software you need for Python web scraping is a code editor. The function of the code editor is to create, modify, and save program files. In addition, the code editor can identify and highlight any errors in your code. As a result, it optimizes your productivity and makes the process of writing codes for Python web scraping more efficient.
NB: Read the official documentation on how to install Python and any code editor you choose. They come with explanations that may be useful in helping you solve some challenges associated with Python web scraping.
Install Python web scraping libraries
Python web scraping libraries are central to creating a script to retrieve data from web pages. Since there are several Python web scraping libraries, you need to study them extensively to understand the best option for you. As discussed in the earlier parts of this guide, these Python web scraping libraries have unique features, strengths, and limitations.
Python request library is a popular package that allows you to send and receive HTTP requests. It is often used with other libraries to maximize Python web scraping activities. In addition, you can use this Python web scraping package to download the HTML codes from the website you want to scrape data from.
In other words, the requests get ( ) function is used to perform an HTTP GET request to the target page URL, and get ( ) responds with the Python representation containing the HTML document.
Another frequently used Python web scraping package is BeautifulSoup, which allows you to extract data from LXML and HTML files.
Create a Folder
After installing these Python web scraping packages, create a new folder on your computer. This folder will contain all the documents for the project. It is essential to have these codes saved in case you need to make modifications.
Test the script
The next step is to import the Python web scraping packages you installed earlier. Before you apply the code to large-scale data collection, it is best to test it on a small scale. This is to identify any errors and make necessary changes before attempting to scrape a large amount of data.
After successful importation of the scripts, add the URL of the website you want to collect data from and execute a fetch request.
To test the script, open your terminal and run the command to begin the test process. Once you are sure the code works, you need to add a # before the “Print” command. This is necessary to prevent the code from rerunning in the future.
Retrieve web data using the script
This is the stage where you get the data you actually want with Python web scraping. To retrieve data, you need to parse the HTML content with a parsing library such as BeautifulSoup. Parsing involves analyzing the HTML structure of a website to understand its elements. BeautifulSoup is equipped with tools for creating and modifying parsed trees.
The next step is to identify HTML elements by leveraging suitable Python web scraping libraries. Writing the script is often described as the heart of Python web scraping activities. It involves developing a set of instructions for your code on how to retrieve data from HTML elements on the web page.
In addition, you can customize the code with the appropraite Python web scraping package. Therefore, you can scrape data from multiple pages by setting a queuing command. To do this, identify anchor tags (<a>) that contain links to additional pages. Then, add these links to a queue before you begin the Python web scraping process on the website. The process continues until the queue is empty and all the pages have been scrapped.
Save the scraped data
The stage of data storage is one of the less confusing aspects of Python web scraping. However, you need to create a list for storing the data. Here are some of the Python codes that maximize data storage:
titles = []
urls = []
time = []
The browser may store the retrieved data in CSV format or JSON format.
How to Parse Text from Any Website
You can parse text from any website using any of the powerful Python web scraping libraries. Here is how to do it.
Step 1: Install and import the required Python web scraping libraries
Although there are various Python web scraping libraries, two are the most popular for this activity. They include requests and BeautifulSoup. The request library is necessary for making HTTP requests to the website you want to retrieve their data. On the other hand, BeautifulSoup is an excellent Python parsing library.
Step 2: Send an HTTP request
After installing and importing the Python web scraping packages, you can use the request library to send an HTTP request to various websites. The get ( ) function of the request package makes it easy to send and receive responses from web pages.
Step 3: Use the response to create a BeautifulSoup object
Once you have received the HTML response, you can leverage the BeautifulSoup library to parse it. This is quite a straightforward process of Python web scraping- create a new BeautifulSoup object and pass the response as an argument.
Step 4: Find the page elements
The next step is to find the elements on the page containing the data you want to extract. You can only find the elements once you have derived the BeautifulSoup object. The find ( ) and find all ( ) methods allow you to quickly identify the elements on a website.
Step 5: Extract the text
At this stage, you are ready to extract the text with Python web scraping. Once you have found all the elements on the page, you can use the .text property to scrape the text you need from any web page.
Step 6: Save the retrieved text
Saving the extracted data is a critical aspect of using Python web scraping to parse text from any website. You can either save it on your computer as a new file or print it to the console.
Suppose we want to parse the title of a website. This is an example of how it should look:
import requests
from bs4 import BeautifulSoup
# Send an HTTP request to the URL of the website
response = requests.get(“https://www.example.com”)
# Create a BeautifulSoup object from the HTML response
soup = BeautifulSoup(response.content, “html.parser”)
# Find the element on the page that contains the title of the website
title_element = soup.find(“title”)
# Extract the title of the website from the element
title = title_element.text
# Print the title of the website
print(title)
