Parsing HTML using Python: A Comprehensive Guide to Extracting Data from HTML Documents
When working with HTML data, parsing it into a format that is easy to work with can be crucial. Python offers several modules that can assist with this task, particularly by enabling you to extract tags as Python lists, dictionaries, or objects.
One of the widely used libraries for HTML parsing is BeautifulSoup. It provides a convenient way to navigate and manipulate HTML documents, providing a natural and intuitive interface. To parse HTML using BeautifulSoup, you can use code similar to the following:
