A sample code that can convert Integer to Roman numeral in Python (not the fastest, but still it works; kind of)

int_to_roman_number.py

def int_to_roman_num(number:int) -> str:
    num, string, lst = str(number)[::-1], 'IVXLCDM', []

    for index, val in enumerate(map(int, num)):
        if val == 0: continue
        (q, r), index2 = divmod(val, 5), index*2
        if val in (4, 9):
            temp = f'{string[index2]}{string[index2+q+1]}'
        else:
            temp = f'{string[index2+q]*q}{string[index2]*r}'
        lst.insert(0, temp)

    return ''.join(lst)

I know its not the best, but I just did it to test myself
