julia> pick_element_from_vector([1,2,3,4], 2)
2

julia> pick_element_from_vector(["a","b","c"], 3)
"c"

julia> pick_element_from_vector([1,2,3,4], 0)
ERROR: BoundsError: attempt to access 4-element Vector{Int64} at index [0]
[...]

pick_last_element(vec::Vector{<:Any}, args...)

Returns the element last element in vec. Throws BoundsError if the vector is empty

julia> pick_last_element([1,2,3,4])
4

julia> pick_last_element([(1,2),(2,2)])

julia> pick_last_element([])
