'looks like you've solved it'

This is awesome!

Because your code did not pass the test? ;-)

My output the function even shows up in console as a print from the return with the correct digit :)

WORKS IN IDE but not online?

Py-3.6.3

STDERR -->

Traceback:
in
AttributeError: 'list' object has no attribute 'describe'

def stray(arr):
i=0
while i <= len(arr):
if arr.count(arr[i]) < 2:
return arr[i]
else:
i+=1
return "No odds"

test = [1,2,2,2,2,2]
print(str(stray(test)))

Can someone please help me as to why it's not passing the test? I have it set up outputting the correct data?
