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

Write a simple code which takes the number, decreases the number, and appends its corresponding value in Roman numerals in a list and finally converts it in the string. This should work for range 1 to 3999

for no in range(1,3999):
    r_st=list()
    a=no
    while(no>1000):
        r_st.append("M")
        no-=1000
    if(no>899 and no<1000):
        r_st.append("CM")
        no-=900
    if(no>499):
        r_st.append("D")
        no-=500
    if(no>399):
        r_st.append("CD")
        no-=400
    while(no>99):
        r_st.append("C")
        no-=100
    if(no>89):
        r_st.append("LC")
        no-=90
    if(no>50):
        r_st.append("L")
        no-=50
    if(no>39):
        r_st.append("XL")
        no-=40
    while(no>9):
        r_st.append("X")
        no-=10
    if(no>8):
        r_st.append("IX")
        no-=9
    if(no>4):
        r_st.append("V")
        no-=5
    if(no>3):
        r_st.append("IV")
        no-=4
    while(no>0):
        r_st.append("I")
        no-=1
    r_st=''.join(r_st)
    print(a,"==",r_st)
