Using split is one way, you can do so with regular expression also like this:

paragraphs = re.search('(.+?\n\n|.+?$)',TEXT,re.DOTALL)

The .+? is a lazy match, it will match the shortest substring that makes the whole regex matched. Otherwise, it will just match the whole string.

So basically here we want to find a sequence of characters (.+?) which ends by a blank line (\n\n) or the end of string ($). The re.DOTALL flag makes the dot to match newline also (we also want to match a paragraph consisting of three lines without blank lines within)
