Spelling Backwards in python

Question

Hi i was doing a code project of the intermediate python course and i have already solved it but my question is:
Is there a way to print the text backwards without changing it? like printing it as the function runs
===================================================================
NEXT IS THE CODE PROJECT STATEMENT:
Spelling Backwards
Given a string as input, use recursion to output each letter of the strings in reverse order, on a new line.
Sample Input
HELLO
Sample Output
O
L
L
E
H
Complete the recursive spell() function to produce the expected result.
===================================================================
MY SOLUTION:
def spell(txt):
#your code goes here
def reverse(txt):
if len(txt) == 0:
return txt
else:
return reverse(txt[1:]) + txt[0]
txt = reverse(txt)
for i in txt:
print(i)
return
txt = input()
spell(txt)
===================================================================
I would like to know how you would have solved it or other ways to solve that problem

Answer 1

No loop or recursion required:
def reverse(txt):
return txt[::-1]
-----
Short version of your program:
print(*list(input()[::-1]), sep='\n')
Input: HELLO
Output:
O
L
L
E
H

Answer 2

for i in input()[::-1]:
print(i)
