Dear Programmers, 
Thank you for your advice regarding giving the console a current address in the code for it to access the html file. 

The console seems to accept the code to that extent, but when I input the two lines of code intended to access the location of a required word, the console rejects it re :

AttributeError:'NoneType' object has no attribute 'li' 

However the document 'EcologicalPyramid.html' does contain the words 'li' and 'ul', in its text. I am not sure as to how the input is arranged to output 'plants' which is also in the documents text, but that is the word the code is meant to elicit. 

I enclose the pertinent code as input and output from the console, and the html code for the document 'EcologicalPyramid.html'

Thank you in advance for your help.

    producer_entries = soup.find("ul")
