Python Python Collections (2016, retired 2019) Slices Slice Functions

Using slices to only show odd indexes.

"Amazing! I know that one can be a little tricky!

OK, try this one on for size: create a new function named odds that returns every item with an odd index in a provided iterable. For example, it would return the items at index 1, 3, and so on."

All the steps before passed fine, and I haven't touched that code - just added new code for each step of the challenge.

I can't see what I've done wrong with the last step (the challenge question is at the top of this post)

Thanks in advance for any help!

slices.py
def first_4(item):
    return item[0:4]

def first_and_last_4(itera):
    first = itera[0:4]
    last = itera[-4:]
    return first+last

def odds(index):
    return index[1::2]

You code looks good to me. :+1: So I pasted it directly into the challenge and it passed the first 3 tasks.

I've heard sometimes browsers can cause false failures. Try restarting your browser and then re-do the challenge.

Can't believe I didn't think to try that! Just restarted the browser and it's gone through fine now! Many thanks
