• 39 = XXX + IX = XXXIX.
• 246 = CC + XL + VI = CCXLVI.
• 789 = DCC + LXXX + IX = DCCLXXXIX.
• 2,421 = MM + CD + XX + I = MMCDXXI.
• 160 = C + LX = CLX
• 207 = CC + VII = CCVII
• 1,009 = M + IX = MIX
• 1,066 = M + LX + VI = MLXVI
• 1776 = M + DCC + LXX + VI = MDCCLXXVI
• 1918 = M + CM + X + VIII = MCMXVIII

def Roman(number):
    numbers = {1000: 'M', 900: 'CM', 500: 'D', 400: 'CD', 100: 'C', 90: 'XC', 50: 'L', 40: 'XL', 10: 'X', 9: 'IX',
               5: 'V', 4: 'IV', 1: 'I'}
    rom = ""
    for key in numbers.keys():
        count = int(number / key)
        rom += numbers[key] * count
        number -= key * count
    return rom
