Python: Compute the sum of non-zero groups (separated by zeros) of a given list of numbers
Python List: Exercise - 210 with Solution
Write a Python program to compute the sum of non-zero groups (separated by zeros) of a given list of numbers.
def test(lst): result =  ele_val = 0 for digit in lst: if digit == 0: if ele_val != 0: result.append(ele_val) ele_val = 0 else: ele_val += digit if ele_val>0: result.append(ele_val) return result nums = [3,4,6,2,0,0,0,0,0,0,6,7,6,9,10,0,0,0,0,0,7,4,4,0,0,0,0,0,0,5,3,2,9,7,1,0,0,0] print("\nOriginal list:") print(nums) print("\nCompute the sum of non-zero groups (separated by zeros) of the said list of numbers:") print(test(nums))
Original list: [3, 4, 6, 2, 0, 0, 0, 0, 0, 0, 6, 7, 6, 9, 10, 0, 0, 0, 0, 0, 7, 4, 4, 0, 0, 0, 0, 0, 0, 5, 3, 2, 9, 7, 1, 0, 0, 0] Compute the sum of non-zero groups (separated by zeros) of the said list of numbers: [15, 38, 15, 27]

Python: Tips of the Day
When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.
For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.
print(1000 // 300) print(1000 / 300)
