I keep defining my function as 'reverse_text', but it keeps erroring

what am I doing wrong here?

code_challenges/templatetags/extras.py
from django import template

register = template.Library()

def reverse_text(s):
    str = reverse(s)
    return reverse(str)

You may be thinking of the built-in function reversed (with a "d").

This function return an iterable, which means to get a string, you will have to first consume the iterable into a list, then use the "".join() string function to combine the list into a string that can be returned.

This will pass the challenge, but a simpler solution is possible using a slice to reverse the string. Can you think of how?

Post back if you need more help. Good luck!!
