Python: Cumulative sum of the elements of a given list

Python List: Exercise - 267 with Solution

Write a Python program to get the cumulative sum of the elements of a given list.

Sample Solution:

Python Code:

from itertools import accumulate
def cumsum(lst):
  return list(accumulate(lst))
nums = [1,2,3,4]
print("Original list elements:")
print(nums)
print("Cumulative sum of the elements of the said list:")
print(cumsum(nums)) 
nums = [-1,-2,-3,4]
print("\nOriginal list elements:")
print(nums)
print("Cumulative sum of the elements of the said list:")
print(cumsum(nums))

Sample Output:

Original list elements:
[1, 2, 3, 4]
Cumulative sum of the elements of the said list:
[1, 3, 6, 10]

Original list elements:
[-1, -2, -3, 4]
Cumulative sum of the elements of the said list:
[-1, -3, -6, -2]
