Ok - the modules issue is solved! Now I have additional issues.

This is the code I'm trying to run - thank you Lars60+

I get the following traceback errors.

bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?

I've installed 'Parsy' for my parser. Should I use something else? The rest of it - I have no clue.

As always, any help is appreciated!

Thanks!

soup = BeautifulSoup(f.read(), 'lxml')

This mean that BS use lxml as parser.
Install lxml.

pip install lxml

Ok - GREAT! No more traceback errors! Thank you!!

Now - it doesn't return anything though. Should I open a new case?

Here is what I get...
