Python: Sum of two lowest negative numbers of a given array of integers
Python List: Exercise - 213 with Solution
Write a Python program to calculate the sum of two lowest negative numbers in a given array of integers.
An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers.
Sample Solution-1:
Python Code:
def test(nums):
result = sorted([item for item in nums if item < 0])
return result[0]+result[1]
nums = [-14, 15, -10, -11, -12, -13, 16, 17, 18, 19, 20]
print("Original list elements:")
print(nums)
print("Sum of two lowest negative numbers of the said array of integers: ",test(nums))
nums = [-4, 5, -2, 0, 3, -1, 4 , 9]
print("\nOriginal list elements:")
print(nums)
print("Sum of two lowest negative numbers of the said array of integers: ",test(nums))
Sample Output:
Original list elements: [-14, 15, -10, -11, -12, -13, 16, 17, 18, 19, 20] Sum of two lowest negative numbers of the said array of integers: -27 Original list elements: [-4, 5, -2, 0, 3, -1, 4, 9] Sum of two lowest negative numbers of the said array of integers: -6

Sample Solution-2:
Python Code:
def test(nums):
return sum([el for el in sorted(nums) if el < 0][:2])
nums = [-14, 15, -10, -11, -12, -13, 16, 17, 18, 19, 20]
print("Original list elements:")
print(nums)
print("Sum of two lowest negative numbers of the said array of integers: ",test(nums))
nums = [-4, 5, -2, 0, 3, -1, 4 , 9]
print("\nOriginal list elements:")
print(nums)
print("Sum of two lowest negative numbers of the said array of integers: ",test(nums))
Sample Output:
Original list elements: [-14, 15, -10, -11, -12, -13, 16, 17, 18, 19, 20] Sum of two lowest negative numbers of the said array of integers: -27 Original list elements: [-4, 5, -2, 0, 3, -1, 4, 9] Sum of two lowest negative numbers of the said array of integers: -6
