are you looking for a line that's equal to "my particular string", or a list that
*contains* "my particular string".

if the former, use

    index = lines.index("my particular string\n") # note the trailing newline

if the latter, you have to loop over the lines, and call the find method on each
one of them (alternatively, if all you want to know if "my particular string" is
anywhere in the file, just load the *entire* file using myfile.read(), and use find
on the entire file)
