Here's the error message.
"Oops, try again. Your function fails on anti_vowel("Hey look Words!"). It returns "Hy lk Words!" when it should return "Hy lk Wrds!"."
I tried running the same code through the builder in sublime text 2 and the output was the same ("Hy lk Words!"). Here's my code as a reference:
for n in text:
for x in wrd:
if x in "aeioouAEIOU" or x == "o":
return ''.join(map(str, wrd))
