Beautiful Soup is a Python package for parsing HTML and XML documents (including having malformed markup, i.e. non-closed tags, so named after tag soup). It creates a parse tree for parsed pages that can be used to extract data from HTML,[2] which is useful for web scraping.[1]

Beautiful Soup was started by Leonard Richardson, who continues to contribute to the project,[3] and is additionally supported by Tidelift, a paid subscription to open-source maintenance.[4]

It is available for Python 2.7 and Python 3.
