Python: Find the largest negative and smallest positive numbers
Python Programming Puzzles: Exercise-79 with Solution
Write a Python program to find the largest negative and smallest positive numbers (or 0 if none).
Input: [-12, -6, 300, -40, 2, 2, 3, 57, -50, -22, 12, 40, 9, 11, 18] Output: [-6, 2] Input: [-1, -2, -3, -4] Output: [-1, 0] Input: [1, 2, 3, 4] Output: [0, 1] Input: [] Output: [0, 0]

def test(nums):
pos = [n for n in nums if n > 0]
neg = [n for n in nums if n < 0]
return [max(neg) if neg else 0, min(pos) if pos else 0]
nums=[-12, -6, 300, -40, 2, 2, 3, 57, -50, -22, 12, 40, 9, 11, 18]
print("List of numbers:",nums)
print("Largest negative and smallest positive numbers (or 0 if none) of the said list:")
print(test(nums))
nums=[-1, -2, -3, -4]
print("\nList of numbers:",nums)
print("Largest negative and smallest positive numbers (or 0 if none) of the said list:")
print(test(nums))
nums=[1, 2, 3, 4]
print("\nList of numbers:",nums)
print("Largest negative and smallest positive numbers (or 0 if none) of the said list:")
print(test(nums))
nums=[]
print("\nList of numbers:",nums)
print("Largest negative and smallest positive numbers (or 0 if none) of the said list:")
print(test(nums))
Sample Output:
List of numbers: [-12, -6, 300, -40, 2, 2, 3, 57, -50, -22, 12, 40, 9, 11, 18] Largest negative and smallest positive numbers (or 0 if none) of the said list: [-6, 2] List of numbers: [-1, -2, -3, -4] Largest negative and smallest positive numbers (or 0 if none) of the said list: [-1, 0] List of numbers: [1, 2, 3, 4] Largest negative and smallest positive numbers (or 0 if none) of the said list: [0, 1] List of numbers: [] Largest negative and smallest positive numbers (or 0 if none) of the said list: [0, 0]
