You're trying to extract "is" from "here is some text"? You already have
"is" in your example, so I'll assume your intent is more complex. Try this:

    >>> text = "here is some text"
    >>> seek = "is"
    >>> start = text.find(seek)         # you don't need 'string' in 1.6
    >>> theWord = text[start : start + len(seek)]
    >>> theWord
    'is'

Is the slicing operation (sequence[start:end]) what you're looking for?
(Note that a slice includes the start, but does *not* include the end.)
