What is web scraping?

Web scraping is a sophisticated method for extracting valuable information from websites. While it's possible to collect data manually, the process is often laborious, time-consuming, and prone to errors. In contrast, web scraping offers a faster, more efficient, and highly accurate way to automate this task.


One of the most significant advantages of web scraping is its ability to capture non-tabular or poorly structured data from websites and transform it into a structured, usable format. This can include converting the extracted data into formats like .csv files or spreadsheets, making it readily accessible for analysis and other applications.


However, web scraping is not merely about data collection but also a powerful tool for data archiving and monitoring changes to online data sources. By automating the process, users can effortlessly keep track of dynamic web content and ensure they always have the most up-to-date information at their fingertips.



Data collection

To acquire preliminary information regarding nightwear products, we utilized our proprietary data scraping platform to collect publicly available data from Marks and Spencer. Python and the BeautifulSoup library were used for extracting the data through web scraping.

  • The extracted data was saved to a CSV file using the Pandas library for easy manipulation and analysis.

  • The CSV file was integrated into an SQLite database to enhance data management.

  • Column field data types in the database were adjusted to match the respective columns.

  • The SQLite database was connected to Metabase, a business intelligence and analytics tool.

  • Metabase was utilized to create analytics charts by adding relevant fields and applying filters.

Attributes Scraped

The following data are extracted from each product present in Marks and Spencer women's lingerie

  • Brand Name: The name of the product

  • Title: The Category/Type of the product

  • Product URL: The URL of the product

  • Average rating: Average number of ratings available for the product

  • Product Code: Product code specified for each product

  • Reviews: Number of reviews each product received

  • Selling Price: The current selling price of the product

  • Original price: The maximum retail price of the product

  • Discount: Difference between the original price and the selling price

  • Sales status: The list of products that are on sale

  • Composition: Inventory of materials employed in the production of the product

This Python script is designed to scrape data from a Marks & Spencer (M&S) website related to lingerie and nightwear products. It uses various libraries, such as requests, BeautifulSoup, pandas, regular expressions, and others, to extract, clean up, and export product information from web pages.


Requests is a popular Python library for making HTTP requests to web pages. In the script, it is used to send HTTP GET requests to URLs, allowing the retrieval of the HTML content of web pages. Once the content is obtained, it can be parsed using BeautifulSoup, enabling the extraction of specific data or information from the web pages. This combination of Requests and BeautifulSoup is a common approach in web scraping and data extraction tasks in Python, making it a powerful tool for interacting with web resources.


Beautiful Soup is a versatile library for parsing HTML and XML documents. In the script, it plays a crucial role in handling the HTML content of web pages retrieved through Requests. By using BeautifulSoup, the script can effectively navigate and parse the structure of these web pages. This capability empowers the script to locate and extract specific elements, data, and information within the HTML, facilitating the extraction of valuable data from web resources. Whether it's scraping data from websites or performing web-related data processing tasks, BeautifulSoup is a valuable tool for developers working with HTML and XML documents in Python.


Pandas is a robust data manipulation library in Python, renowned for providing versatile data structures such as Data Frames. These data frames are instrumental for managing and analyzing structured data efficiently. In the script, Pandas finds application in the creation and manipulation of Data Frames, serving as a means to store and organize the product data obtained through web scraping. Leveraging Pandas in this context simplifies the process of working with and structuring the scraped data. Moreover, it facilitates various data analysis and transformation tasks, and Pandas' ability to export data to popular formats like CSV proves invaluable in making the data accessible and usable for a wide range of applications.


The 're' library, short for regular expressions, is a built-in Python library designed for handling regular expressions, and powerful tools for pattern matching and text manipulation. In the script, 're' plays a crucial role in the extraction of specific information from text strings acquired from web pages. For instance, it is employed to extract key details such as the number of reviews from a given string. By utilizing regular expressions, the script gains the ability to precisely define and extract structured patterns of text, making it a valuable asset in the process of scraping, parsing, and organizing data from web sources. This capability streamlines data extraction and enables the script to obtain the exact information it needs for further analysis and processing.


The 'os' library, an integral part of Python, serves as a valuable tool for interacting with the operating system, encompassing a wide array of file and directory operations. Within the script, 'os' takes on a pivotal role in various aspects, including the management of the CSV file housing the scraped data. It is used to check whether a file already exists, enabling the script to determine whether it needs to create a new file or append data to an existing one.


Additionally, 'os' is instrumental in handling file operations, such as creating, replacing, or appending to the CSV file as the script demands. This functionality enhances the script's ability to efficiently manage and organize the data it collects and makes it easier to work with the resulting datasets for further analysis or applications.


The 'RequestException' class, which is part of the 'requests.exceptions' module, is a specialized exception class offered by the requests library. Its primary purpose is to facilitate the handling of exceptions associated with HTTP requests. In the script, 'RequestException' is a key component in error management when making HTTP requests. It is used to catch and handle a range of potential exceptions that can arise during these requests, including issues like network errors or timeouts.


By employing 'RequestException,' the script is equipped to gracefully address and manage errors that might occur, ensuring that it can maintain robust execution even in the face of unexpected issues. This error-handling capability is essential for maintaining the script's reliability and ability to collect data from web sources effectively.


In summary, these libraries are essential for various aspects of web scraping, data extraction, data manipulation, and error handling in the script.


Defining Data Storage

Several lists are initialized to store information about each product, including its URL, company, product name, product code, average rating, reviews, selling price, original price, saved price, color, sales status, styles, and composition.


Functions

The script defines several functions for specific tasks, such as extracting HTML content from a URL, extracting the number of pages to scrape, extracting product URLs from pages, and extracting various product details like company, product name, etc.


Main Function:

The main function within the script serves as its central entry point, orchestrating the entire web scraping process. It begins by defining the essential elements: the base URL and the required headers for sending HTTP requests to the M&S website. Subsequently, it initiates the data collection process by first utilizing the extract_href_values function to retrieve the HTML content of the primary product page.


Once this initial data is obtained, the main function calculates the total number of available product pages and then generates the corresponding URLs for each page. With the list of page URLs in hand, it leverages the extract_product_url function to extract the individual product URLs from these pages.


Finally, the script advances to the core task of data extraction, using the fetch_product_details function to scrape and capture specific details of the products. In summary, the main function acts as the command center for the script, systematically executing each step of the web scraping process, ultimately resulting in the retrieval of product data from the M&S website.


Scraping Product Details

Inside the fetch_product_details function, the script iterates through each product URL, sends an HTTP request to the product page, and extracts details such as the company, product name, product code, average rating, reviews, prices, color, sales status, and composition. These details are stored in the respective lists.


Exporting Data

Upon completion of the product data scraping process, the script utilizes the Pandas library to structure and organize the collected information within a DataFrame. Following this organization, the script performs a file operation check to ascertain if a file named 'mas.csv' already exists.


If such a file is present, it is replaced with the updated data; otherwise, the script creates a new CSV file. Subsequently, the final DataFrame, now containing the meticulously gathered product details, is promptly saved to the 'mas.csv' file. This process of exporting the data to a CSV file ensures that the collected information is neatly stored and readily accessible for further analysis, reporting, or any other data-related tasks.


Execution:

The script checks whether it is being executed directly (not imported as a module) and, if so, calls the main function to start the scraping process.

In summary, this Python script scrapes information about lingerie and nightwear products from the M&S website, extracts various details about each product, and exports the data to a CSV file for further analysis or storage.


Extracting Product Information

A series of functions are defined within the script to extract various pieces of information from product pages. These functions work collectively to gather details such as brand name, product name, prices, ratings, the count of ratings, colors, and various other product specifics. Here's an explanation of each of these functions:

  1. The extract_href_values(url, headers, max_retries=3) function accepts a URL, headers, and an optional maximum retry count as input. It sends a GET request to the provided URL with the specified headers and retries up to three times in case of network or request-related issues. It returns the parsed HTML content of the response using Beautiful Soup.

  2. The extract_number_of_pages(soup) function takes the parsed HTML content (soup) as input and seeks a specific element in the HTML that contains information about the number of pages. It extracts and returns the maximum number of pages as an integer.

  3. The extract_product_url(baseUrl, pageUrls, headers) function requires a base URL, a list of page URLs, and headers as input. It iterates through each page URL, sends requests, and extracts product URLs from the HTML content of each page. It returns a list of product URLs.

  4. For brand name extraction, the extract_company function takes the parsed HTML content (soup) as input and attempts to find the brand or company name using specific classes. It returns the name as a string if found, otherwise "Not available."

  5. The extract_product_name function, working with the parsed HTML content (soup), searches for an element containing the product name. If found, it returns the name as a string; otherwise, it returns "Not available."

  6. To extract the product code, the extract_product_code function takes the parsed HTML content as input, searching for an element that contains the product code. It returns the product code as a string if found, or "Not available" if not.

  7. The extract_avg_rating function extracts the average rating from the parsed HTML content (soup). It returns the average rating as a float if found, otherwise None.

  8. For the number of reviews, the extract_reviews function searches for an element in the parsed HTML content (soup) that contains the review count. It returns the number of reviews as an integer if found, or None if not.

  9. The extract_selling_price function focuses on extracting the selling price, removing the currency symbol if present. It takes the parsed HTML content as input and returns the selling price as a float.

  10. The extract_original_price function, working with the parsed HTML content, searches for the original price of a product and returns it as a float if found. In case of absence, it falls back to the selling price.

  11. To extract information about the saved price (discount), the extract_saved_price function looks for the relevant element in the parsed HTML content and returns the saved price as a float if found; otherwise, it returns None.

  12. The extract_color function, using the parsed HTML content, finds the element containing product color information. It returns the color as a string if found, or "Not available" if not.

  13. For sales status, the extract_sales_status function searches for an element indicating the sales status, such as "In stock" or "Out of stock." It returns the sales status as a string if found, or "Not available" if not.

  14. Finally, the extract_composition function, based on the parsed HTML content, seeks an element with information about the product's composition or materials. It returns the composition as a string if found, or "Not available" if not.


Collectively, these functions enable the script to systematically extract a wide range of product details from web pages, facilitating comprehensive data collection and analysis.
