This will truncate a long character based on the given length parameter. If the word is cut-off, it will return the string up until the next space. If there are no spaces in the next 5 characters, that should mean a very long word and we should truncate right away.

    if data.find(' ', arg, arg+5) == -1:
        return data[:arg] + '...'
    else:
        return data[:arg] + data[arg:data.find(' ', arg)] + '...'
