Python：

class Solution(object):
    def intToRoman(self, num):
        """
        :type num: int
        :rtype: str
        """
        digit=["","I","II","III","IV","V","VI","VII","VIII","IX"];
        ten=["","X","XX","XXX","XL","L","LX","LXX","LXXX","XC"];
        hundred=["","C","CC","CCC","CD","D","DC","DCC","DCCC","CM"];
        thousand=["","M","MM","MMM"];
        return thousand[num/1000]+hundred[(num%1000)/100]+ten[(num%100)/10]+digit[num%10];
