    delims parameter is list of delimiter characters. Function returns
    tuple containg word, starting postion of word and ending position
    of word. Given word can be taken from text as text[start:end].
    Example:
        text = "This is line"
        result = ""
        for word in splitter(text, [" "]):
            result = result + text[word[1]:word[2]] + " "

        result = ""
        for word in splitter(text, [" "]):
            result = result + word[0] + " "
        print result
    """
    #stores result
    result = []
    #if delimiter is not specified, use defaults
    if delims == None:
        delims = delimiters
    #starting with empty word

            if len(word) > 0:

            start = i + 1
        else:
            #char is not delimiter, so append it to word
            word = word + text[i]

    #append last word to result

            #word end beyond end of text
            i = i + 1

The variable i does not seem to be defined in case the for loop on line 52 is not entered. Are you sure this can never be the case?

        result.append((word, start, i))
