In this source code example, we will write a python class to convert an integer to a Roman numeral.

Write a python class to convert an integer to a Roman numeral

class py_solution:
 def roman_to_int(self, s):
    rom_val = {'I': 1, 'V': 5, 'X': 10, 'L': 50, 'C': 100, 'D': 500, 'M': 1000}
    int_val = 0
    for i in range(len(s)):
        if i > 0 and rom_val[s[i]] > rom_val[s[i - 1]]:
            int_val += rom_val[s[i]] - 2 * rom_val[s[i - 1]]
        else:
            int_val += rom_val[s[i]]
            return int_val
print(py_solution().roman_to_int('MMMCMLXXXVI'))
print(py_solution().roman_to_int('MMMM'))
print(py_solution().roman_to_int('C'))
print(py_solution().roman_to_int('X'))

Output:

1000
1000
100
10
