Reverse a string without using reversed() or [::-1]?

Question

I came across a strange Codecademy exercise that required a function that would take a string as input and return it in reverse order. The only problem was you could not use

Answer 1

def reverse(text):
    a=""
    l=len(text)
    while(l>=1):
        a+=text[l-1]
        l-=1
    return a

i just concatenated the string a with highest indexes of text (which keeps on decrementing by 1 each loop).
