It's correct, the iterator over a file gives lines not words. But it's
very simple to have an iterator over words. Untested:

def iterword(f):
    """Iterate over the words of a file.

    Args: a file object.
    for line in f:
        #Split the line in words.
        words = line.split()
        for word in words:
            yield word

In splitting the line in words I have used the simplest possible
device: the string method split that splits a string on whitespace.
More sophisticated (and correct) ways of splitting a line in words can
be achieved with the re module, for example.

With my best regards,
G. Rodrigues
