Im not sure how to do this. I get so discouraged that I cant move forward and there are no hints. Can someone show me how to do this? please and thank you. I wish the quizzes didnt span all different lessons. The quizzes are so frustrating
list = [1,2,3,4,5,6]
def first_4(x):
x = [0:5]
return(x)

- you only need to define the functions, you won't need to supply any data
- there should not be an equal sign between the slice brackets and the item being sliced
- you won't need to assign a variable if you create the slice as part of the "return" statement

And happy coding!

18,975 PointsI'm past this challenge already, but I forgot how the third part of this challenge was done. It's asking for the odd index numbers. First, I created an empty list then I for-looped through the range of the length of the list argument . Then I set an if condition where only indexes not divisible by 2(i % 2 != 0) would be added to the empty list. I returned that list and it was wrong.
For the first part of this challenge. I passed when returning [0:4] instead of [0:3]. Isn't [0:3] the first four items?

231,275 PointsThe odd indexes can be obtained using a slice with a start value of 1 and a step of 2 (
[1::2]). All of the tasks in this challenge can be completed without using loops.When using a stop value, the number is for the index to stop before. So
[0:4](or just[:4]) would return the indexes 0,1,2,3 (the first four).Brent Capuano

231,275 PointsBrent – Try applying the hints given here, and if you still have trouble, create a fresh new question where you can show your code as it is now and we can take it from there.
