Answer 1

As long as you're not worried about accidentally finding the word in an element attribute or something (and if you are worried about that, parsing the HTML with something like lxml is kind of your only option), you can just treat the entire HTML document as a big string and search for your word in it:

def checkForWord():
    r = requests.get("http://example.com/somepage.html")
    return "myWord" in r.text

Answer 2

I'd get the entire page as a string:

var markup = document.documentElement.innerHTML;

And, then I'd use a method to search for the string in a string:

var n = markup.search("YourString");

You'll get a number for the index of the match or -1 if no match found.
