I wanted odds in the return. Did I use the wrong syntax or misunderstand the question?

I get odd numbers in the resulting list, but it's not what the question is looking for. I can't see the question at the moment, but it was asking for a function that returns an odd index in the iterable.

slices.py 
def first_4(item):
  my_list=list(range(1,5))
  for item in my_list:
    return my_list[:4]

def odds(odd_item):
  odd_list=list(range(0,20))
  for odd_item in odd_list:
    return odd_list[1::2]

Your odds() function is working too hard. You only have to operate on the iterable passed in:

def odds(odd_item):
    #odd_list=list(range(0,20))
    #for odd_item in odd_list:
    return odd_item[1::2] #<-- changed to operate on the input parameter
