You're still posting in html, not text.  I stripped out the markup
portion of your message, but you're still left with lots of invisible
characters in the following. Your email program is stuffing "\xa0"
characters in place of every other space, which cuts the indentation
in half.

Here's the html in your message for just one of the lines below:

<div>    infile.close()</div>

In the text version, it looks approximately like this:

_ _ infile.close()

some readers will just show it as
  infile.close()


When you compose your message in your email program, please mark it as a
text message in your email program. Otherwise you can never be sure
what each of us will see.

I have no idea how that function will be useful.  It makes much more
sense to me to strip the entire file, then split it into a list of
words.  Then you loop through that list of words, seeing which of those
words match your sample word.

But that's not what the assignment called for.  You shouldn't be
splitting on lines, but on words.  Otherwise, how are you going to
handle a line that starts with the word river?  Make a single list
containing all the words in the file.

Well, it prints the same thing because you're printing "words", rather
than "word."  And of course if you wanted to actually see the index
working, you'd have to print that as well.

for index, word in enumerate(words):
    print(index, word)
