Write a script/function/program that converts a user inputted number or Roman numeral to its equivalent?

1) Write a script/function/program that converts a user inputted number or Roman numeral to its equivalent.

Recall Roman Numerals where:

 I = 1 
 V = 5
 X = 10
 L = 50 
 C = 100
 D = 500 
 M = 1000

Also remember IX is 9 (10 - 1) while XI = 11 (10+1) but XIX = 19 (10+9)

Most likely you will use the following function: str = input('Roman numeral: ','s')

Just to clarify -- your program should prompt a user to convert a Roman numeral into it’s numerical equivalent or take a number and output the equivalent Roman numeral.
