from List to BeautifulSoup , Homework

[RPC]

I did not include the information in the forum because, there are almost 1500 lines of code. in the HTML

But my question is how to convert either from a list to a BeautifulSoup,...
or from a string to a BeautifulSoup.... in order to use find_all and be able to parse .

I really appreciate your help.

I am looking for it on the web,, if i find something i will post it. But if anyone here has a previous experience with it, it will be very useful.

Thanks in advance
