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
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
