Oops, try again. Your function fails on reverse("Python!"). It returns "None" when it should return "!nohtyP".
This seems to work perfectly fine when I execute the code in PyCharm. For whatever reason, the lesson doesn't seem to like the submission. Any thoughts? I've read other posts and gotten other solutions to work, but this seemed more intuitive to me. Thanks in advance for any feedback.
def reverse(text): backwards =  for letter in text: backwards.insert(0,letter) end = "" for item in backwards: end += item print end
