6) Write a function allbut(a_list, index), which takes as arguments a list and an index, and returns a new list with all elements of the argument list (in the order they were) except for the element at index. The argument list should not be modified by the function. my_list=[1,2,3,4,5,6] my_short_list allbut(my_list, 3) print(my_short_list) print(my_list) # [1, 2, 3, 5, 6] #[1, 2, 3, 4, 5, 6]
