Delete x-line paragraphs from text file with Python
<p>I have a long text file with paragraph with 6 and 7 lines each. I need to take all seven line paragraphs and write them to a file and take six line paragraphs and write them to a file. 
Or delete 6-line (7-line) paragraphs.
Each paragraph is separated with blank line (or two blank lines). 
Text file example:</p>

<pre>
Firs Name Last Name

Address2
Note 1
Note 2
Note3
Note 4

First Name LastName
add 1

Note4

etc...

</pre>
