# (Solved) : Write Two Functions Python One Converts Number Roman Numeral Converttoroman Converts Back Q42722531 . . .

Write two functions in Python. One that converts a number to aRoman Numeral (convertToRoman), and the other converts it back to anumber(convertFromRoman).

I. Given a number, return a Roman Numeral string. (20points)

1. Any number <= 0, throws “Error – Too Small”.
2. Any number > 3,999, throws “Error – Too Large”.
3. Any value that is not a number, throws “Error – Not aNumber”.
4. Use standard values(en.wikipedia.org/wiki/Roman_numerals).

1 = I 7 = VII 40 = XL 100 = C 700 = DCC 74 = LXXIV

2 = II 8 = VIII 50 = L 200 = CC 800 = DCCC 299 = CCXCIX

3 = III 9 = IX 60 = LX 300 = CCC 900 = CM 2019 = MMXIX

4 = IV 10 = X 70 = LXX 400 = CD 1000 = M

5 = V 20 = XX 80 = LXXX 500 = D 2000 = MM

6 = VI 30 = XXX 90 = XC 600 = DC 3000 = MMM

Examples:

convertToRoman(812) returns “DCCCXII”

convertToRoman(49) returns“XLIX”

convertToRoman(5000) throws“Error – Too Large”

II. Given a Roman Numeral String, parse it and return thenumber. If it does not match a legal number from above (in therange 1 to 3,999), throw “Error”. (40 points)

Examples:

convertFromRoman(“CCCXIV”)returns 314

convertFromRoman(“MCMXCIX”)returns 1999

convertFromRoman(“CXXXXI”) throws“Error”

convertFromRoman(“ I ”) throws“Error”

convertFromRoman(“MMMM”) throws“Error”
