Ok, here, regex for roman numerals:
 >>> pattern = """
     ^                   # beginning of string
     M{0,4}              # thousands - 0 to 4 M's
     (CM|CD|D?C{0,3})    # hundreds - 900 (CM), 400 (CD), 0-300 (0 to 3 
C's),
                         #            or 500-800 (D, followed by 0 to 3 C's)
     (XC|XL|L?X{0,3})    # tens - 90 (XC), 40 (XL), 0-30 (0 to 3 X's),
                         #        or 50-80 (L, followed by 0 to 3 X's)
     (IX|IV|V?I{0,3})    # ones - 9 (IX), 4 (IV), 0-3 (0 to 3 I's),
                         #        or 5-8 (V, followed by 0 to 3 I's)
     $                   # end of string
     """
