Never put any user files in the "python 2.8" directory, whatever that is.

Since your code expects it in the current directory, either change the 
code, or make sure it IS in the current directory.

The only obvious thing I can see is that you didn't spell the name the 
same.  But since Windows makes the error of ignoring case, it ought to 
be close enough.  However, you're typing the name, not pasting it, so 
maybe there's some other subtle difference, like you have more than one 
Soup directory.

Try the following, from the cmd.exe prompt:

myprompt> cd Soup
myprompt> dir *.html
   (something shows here)
myprompt> python
   (something shows here)


 >>> from bs4 import BeautifulSoup
 >>> with open("ecologicalpyramid.html","r") as ecological_pyramid:
...      soup= next(ecological_pyramid,"lxml")
...      producer_entries = soup.find("ul")
...

and see what happens.  Paste the whole thing into a message if it 
doesn't make sense to you.  And of course don't forget to include the 
traceback.
