Thank you for your contribution to solving issue #70 by returning the full text of the article. The changes are heading in the right direction. Here are a few suggestions to improve the implementation:

Documentation Update:
The docstring for the get_full_article method needs to be updated to reflect the new behavior accurately. The current docstring mentions returning an Article object, but now the method returns the full text of the article.

Error Handling:
When the article text is less than 200 characters, the function attempts to use BeautifulSoup to parse the HTML. It's a good approach, but we should add a check to ensure that article.html is not None before parsing.
