We define a list of data objects in the code above, each of which has a URL and several views. For instance, you might want to examine online traffic by domain to identify the most popular domains.ĭomains = ĭomains.append(d)

Organizing data by domain is frequently helpful when studying web data. Afterwards, we exclude invalid domains and only scrape information from URLs with valid domains. The urlparse module is used in the code above to extract the domain names from the list of URLs to scrape. If urlparse(url).netloc in legit_domains:

Here is an illustration of some sample web scraping code that shows how to retrieve the domain from a list of URLs: from urllib.parse import urlparse Also, you can exclude illegitimate domains using the domain information and only scrape data from reputable sources. You may quickly determine if a domain is valid or not by removing the domain from the URL. It’s crucial to confirm that the data being scraped from the web came from a reliable source.

The URL from which we wish to extract the domain is specified, and the exact function is used to extract the domain’s constituent parts. The tldextract module, which has a parse function for removing domain components from a URL, is first imported in the code above. Here is an example of some code that uses tldextract to extract the domain from a URL: import tldextract This third-party library’s ability to extract a URL’s top-level domain (TLD), domain name, and subdomains makes it very helpful. The tldextract module can also be used to extract the domain from a URL. We locate the pattern in the URL using the re.search function, then we utilize the named group (?P) to extract the domain. Print(domain) # Output: 'The re module, which offers functionality for regular expressions, is first imported in the code above.įollowing that, we specify the URL from which we wish to extract the domain and develop a regex pattern that recognizes domain names. If you need to extract the domain from a URL that doesn’t adhere to a conventional format, this method can be quite helpful. You can extract the domain from a URL by matching it with a specified pattern if you prefer regular expressions (regex). The URL is broken down into its component parts using the urlparse function, and the domain is extracted from the netloc attribute. The URL from which we want to extract the domain is then defined. Print(domain) # Output: 'The urlparse module is first imported into the code above from the urllib.parse library. Here is an illustration of code that uses urlparse to extract the domain from a URL: from urllib.parse import urlparse This module offers several functions for breaking down URLs into their constituent parts, such as the domain. Using the included Python package urlparse is one simple method for obtaining the domain from a URL. Three popular techniques for obtaining domains from URLs in Python will be covered in this section along with useful examples. Python fortunately offers various options for doing this.
