Python Script for Roman Numerals
 Here a python script for Roman Numerals:     romanNumerals = {'I': 1, 'V': 5, 'X': 10, 'L': 50, 'C': 100, 'D': 500, 'M': 1000}     def getRomanNumerals(value):       string = value.upper()         total = 0       while string:           if len(string) == 1 or romanNumerals[string[0]] >= romanNumerals[string[1]]:               total += romanNumerals[string[0]]               string = string[1:]           else:               total += romanNumerals[string[1]] - romanNumerals[string[0]]               string = string[2:]       return total     getRomanNumerals(!FieldName!)
