I can't find the value of the “k” smallest integer in "n" amount of integers in a list

Question

n = input('print n：')
k = input('print k')
a = input('print'+str(n)+'numbers：')
s = str(a)
Lst = s.split()
map_object = map(int, Lst)
lst = list(map_object)

I have the rest done, and I don't know how to find and print the k smallest integer.

inputs:

10(n) 3(k)

1 3 3 7 2 5 1 2 4 6(n amount of numbers)

outputs:

3

That's a matrix, and this is a list. unfortunately, I have not learned matrixes yet. — I am amazing, Dec 01 '20 at 22:47

You can have duplicate numbers, so first we are getting rid of them by using set():

no_duplicates = set(lst)

Then we sort it, which will return us sorted list:

sorted_list = sorted(no_duplicates)

Then we get your desired number (you haven't converted k to int, so we will do it here):

kth_smallest = sorted_list[int(k)-1]

When i added the codes below my original codes, it said unsupported operand type(s) for Sub: 'str' and 'int' on line 15 – I am amazing Dec 01 '20 at 22:58
just write `print(kth_smallest)` – Tugay Dec 01 '20 at 23:00

Nope. Still said unsupported operand type(s) for Sub: 'str' and 'int' on line 15. – I am amazing Dec 01 '20 at 23:02

wait! i added int() to k then it worked! – I am amazing Dec 01 '20 at 23:03
huh, okay, my mistake, I will edit answer – Tugay Dec 01 '20 at 23:04
