Python: Filter for the numbers in a list whose sum of digits is >0, where the first digit can be negative
Python Programming Puzzles: Exercise-47 with Solution
Write a Python program to filter for numbers in a given list whose sum of digits is > 0, where the first digit can be negative.
Input: [11, -6, -103, -200] Output: [11, -103] Input: [1, 7, -4, 4, -9, 2] Output: [1, 7, 4, 2] Input: [10, -11, -71, -13, 14, -32] Output: [10, -13, 14]
Sample Solution:
Python Code:

def test(nums):
return [n for n in nums if int(str(n)[:2]) + sum(map(int, str(n)[2:])) > 0]
nums = [11, -6, -103, -200]
print("Original list:")
print(nums)
print("Find the numbers in the said list whose sum of digits is >0, where the first digit can be negative:")
print(test(nums))
nums = [1, 7, -4, 4, -9, 2]
print("\nOriginal list:")
print(nums)
print("Find the numbers in the said list whose sum of digits is >0, where the first digit can be negative:")
print(test(nums))
nums = [10, -11, -71, -13, 14, -32]
print("\nOriginal list:")
print(nums)
print("Find the numbers in the said list whose sum of digits is >0, where the first digit can be negative:")
print(test(nums))
Sample Output:
Original list: [11, -6, -103, -200] Find the numbers in the said list whose sum of digits is >0, where the first digit can be negative: [11, -103] Original list: [1, 7, -4, 4, -9, 2] Find the numbers in the said list whose sum of digits is >0, where the first digit can be negative: [1, 7, 4, 2] Original list: [10, -11, -71, -13, 14, -32] Find the numbers in the said list whose sum of digits is >0, where the first digit can be negative: [10, -13, 14]
