Jake,

That was in an effort to get only the 15most frequent words, if I
understood your earliest post aright. If so, even if the output was correct
for the case, that is by accident. What happens in only 3 distinct words
show up 300 times? If 42 do?

You need to rethink, I think. Do you know how list indexing and list
slicing work?

" a program on the computer"? I assume that you mean file.

What happens if you run

open(" nowayyouhaveafilecalledthiscausethatdbesilly", 'r')

That's rather different than if the path is the path of an existing file,
right. So, you could try to react differently to the two sorts of results.

Do you know how to use try an except?

I shall leave this for others; I'm not ready for my Monday, yet.

Best,
