Python Python Collections (Retired) Slices Slice Functions

Challenge Task incorrect

The expected output for Task 2 in the Slices section of Python Collections is koao. However, the challenge does not specify that 'Oklahoma' is the string needed for the odds function.

Here is the question:

"Make a function named odds that accepts an iterable as an argument and returns the items with an odd index in the utterable."

Can you please update it?

Thank you

slices.py 
def first_4(a_list):
    a_list = list(range(1, 20))
    return a_list[:4]

def odds(odd_list):
    odd_list = 'Oklahoma'
    return odd_list[1::2]

Hi there,

There's no need to define odd_list as "Oklahoma"; that's just what the tests behind the scenes are doing to make sure your output is correct. You don't want to hard-code it. The challenge needs to run your code with a known input (the string "Oklahoma") to ensure that the expcted output is returned. Your code shouldn't specify that - the following is fine: 

def first_4(a_list):
    return a_list[:4]

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

I hope that helps.

Steve.
