Roman Numeral Conversion

MediumPython

Problem

Write two functions: one that converts a number to a Roman numeral and another that converts a Roman numeral back to a number.

Implement int_to_roman(num) and roman_to_int(roman) for canonical Roman numerals from 1 through 3999. For grading, expose convert_roman(num, roman), which returns both results as {"int_to_roman": string, "roman_to_int": integer}.

Constraints

1 <= num <= 3999
roman contains only the characters I, V, X, L, C, D, and M
roman is a canonical Roman numeral representing a value from 1 through 3999
The two input values are independent conversion inputs

Function Signature

def convert_roman(num, roman):
