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 >         


        

Answer 1

Or just use heapq:

import heapq
def second_largest(numbers):
    return heapq.nsmallest(2, numbers)[-1]

second_largest([1, 2, 3, 4])
# Output: 2
