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]

Returns True if the provided function returns True for every element in the list, False otherwise:
Example:
def tips_every(lst, fn=lambda x: x): return all(map(fn, lst)) print(tips_every([2, 4, 3], lambda x: x > 1)) print(tips_every([1, 2, 3]))
