is this a bug?
I successfully completed the first 3 Tasks but because a had a doubt, I went back to open the REPL and do some research. When I came back, now the Task are no longer successful. I believe they are. What should I do? I cant continue the class!!
def first_4(item): return item[:4] def first_and_last_4(item): return item[:4] + item[-4:] def odds(item): return item[1::2] def reverse_evens(item): return item(start::-2)

With the last function
reverse_evens, you're not indexing the list using the square brackets (), you're using the round brackets which means that Python thinks you're calling a function called item. Another issue with this function is that you're referencing a variable called start but there is no start variable defined in your code right now.
