Python - Find second smallest number

Question

I found this code on this site to find the second largest number:

def second_largest(numbers):
    m1, m2 = None, None
    for x in numbers:
        if x >= m1:
            m1, m2 = x, m1
        elif x > m2:
            m2 = x
    return m2

Source: Get the second largest number in a list in linear time

Is it possible to modify this code to find the second smallest number? So for example

print second_smallest([1, 2, 3, 4])
2

Answer 1

a = [6,5,4,4,2,1,10,1,2,48]
s = set(a) # used to convert any of the list/tuple to the distinct element and sorted sequence of elements
# Note: above statement will convert list into sets 
print sorted(s)[1]
