Basic program to convert integer to Roman numerals?

Question

I\'m trying to write a code that converts a user-inputted integer into its Roman numeral equivalent. What I have so far is:

The point of the generate_

Answer 1

The code for this roman numeral does not check for errors like wrong letters it is just for a perfect roman numeral letters

roman_dict = {'M':1000, 'CM':900, 'D':500, 'CD':400, 'C':100, 'XC':90,
         'L':50, 'XL':40, 'X':10, 'IX':9, 'V':5, 'IV':4,'I':1}

roman = input('Enter the roman numeral: ').upper()
roman_initial = roman # used to retain the original roman figure entered

lst = []


while roman != '':    
if len(roman) > 1:
    check = roman[0] + roman[1]
    if check in roman_dict and len(roman) > 1:
        lst.append(check)
        roman = roman[roman.index(check[1])+1:]
    else:
        if check not in roman_dict and len(roman) > 1:
            lst.append(check[0])
            roman = roman[roman.index(check[0])+1:]   
else:
    if len(roman)==1:
        check = roman[0]
        lst.append(check[0])
        roman = ''

if lst != []:
Sum = 0
for i in lst:
    if i in roman_dict:
        Sum += roman_dict[i]
print('The roman numeral %s entered is'%(roman_initial),Sum)
