Write me a the Python program you requested given the following:
Complete the below
def fill(text, width, *args, **kwargs):

    ''''Like :func:`textwrap.wrap` but preserves existing paragraphs which
    :func:`textwrap.wrap` does not otherwise handle well.  Also handles section
    headers.'
    '''

#Here is the Python program you requested.
    paragraphs = text.split('\n\n')
    def maybe_fill(t):
        if all(((len(l) < width) for l in t.splitlines())):
            return t
        else:
            return textwrap.fill(t, width, *args, **kwargs)
    return '\n\n'.join((maybe_fill(p) for p in paragraphs))
