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.

Sample Solution:

Python Code:

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))

Sample Output:

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

Floor Division:

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)

Output:

3
3.3333333333333335
