16,436 PointsHere's how I would approach the problem.
number_list=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
def odds(number):
odd_list = []
for num in number:
if num % 2 == 1:
odd_list.append(num)
print(odd_list)
odds(number_list)
In the function, I created a blank list to which I appended only the numbers that were not evenly divisible by 2. I used the modulus operator.
EDIT: I just saw Kenneth's comment that the challenge is asking for the numbers that have an odd index. I think this will do it:
def odds(number_list):
return number_list[1::2]

Treehouse Guest TeacherThe CC isn't asking for numbers that are odd, but for numbers that have an odd index.

4,246 Pointsi tried this and it works for me
''' def odd(number):
return number[1::2]
'''
however, i dont know how to do the next exercise. Where do i begin?

Treehouse Guest TeacherYou make a function that sends back the first 4, and last 4, items in an iterable. The 4th-from-last item in an iterable can be gotten with [-4].

4,246 Pointsi know that but i dont know how to put that in the expression. Can i make it like this?
''' def first_and_last_4(number): return number [::4:-4] '''

Treehouse Guest TeacherNope, but you can always add two slices together and return that.
