what is the python program to print second smallest elemnt in a list

Answer 1

x.sort() will change your list inside list x, so you cannot go back to the initial order. to avoid it, you can do:

sorted(list(set(x))) [1]

that will not only return second smallest element, but also is immune to lists with repetitions

Answer 2

Sort the list and pick the list[1] element. It's the easiest way
