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

 """
# This program will allow the user to input a number from 1 - 3999 (in english) and will translate it to Roman numerals.

Guys the reason why I wrote this program like that so it becomes readable for everybody. 
Let me know if you have any questions...
