Q: Regexp, Python and doc comments  I am programing in Python 2.7, I am using beautifulsoup4 to extract information from tags of series of documents. However the document has as well strings as: 
<!-- PJG ITAG l=90 g=1 f=4 -->

And I want to get rid of them, however I am not an expert on regexps. Can someone help with this please?

A: Start by loading your HTML in BeautifulSoup:
from bs4 import BeautifulSoup, Comment
soup = BeautifulSoup(the_html)

Then, remove all the comments:
comments = soup.find_all(text = lambda text:isinstance(text, Comment))
for comment in comments:
    comment.extract()
