Very beginner but please help! - thurpe - Jul-31-2018
Hi, I am following a set of exercises, and I got stuck a bit on this one:
Write a function that returns the first and last elements of a list.
My code worked when the list was set, but when I use randomly created list, the command returns the whole list twice.
import random
def listing():
list = [random.sample(range(1,100),10)]
return [list[0], list[-1]]
print(listing())Can you please check?:)thurpe

random.sample returns list. But you put this in square brackets, so it becomes list of lists with one element,e .g.
[[93, 15, 58, 11, 35, 67, 36, 33, 42, 63]]you can easily check this if print it immediately after line 5.
import random
def listing():
lst = random.sample(range(1,100),10)
return [lst[0], lst[-1]]
print(listing())Also, don't use list as variable name. list() is built-in function and using list as a variable name the function is no longer available

I understand, thank you very much for the clarification!
