Reverse a string of characters

Question

I tried this code but I don't know how input the characters one per line and how to stop the input sequence with the character 0.

def reverse(string):
    if len(string) == 0:
        return string
    else:
        return reverse(string[1:]) + string[0]
a = str(input())
print(reverse(a))

Can you be more clear on what you want here? I'm not sure what your actual problem is. — ShadowRanger, Mar 19 '20 at 17:21
Is doing it recursively required or can you just use a oneliner? — Rashid 'Lee' Ibrahim, Mar 19 '20 at 17:21
I need an input one per line and the input sequence with this code dosen't stop with 0. I want the program stops when input value is 0. — d.fox3, Mar 19 '20 at 17:25

In python you can usually reverse an iterable with [::-1]. It should work on strings as well, I guess. So: 'hello'[::-1] gives 'olleh'.
