Program to find the cumulative sum of elements of the list,

In this problem, we will take the list as input from the user. Then print the cumulative sum of elements of the list.

Program to find the cumulative sum of elements in a list

# Python program to find cumulative sum 
# of elements of list

# Getting list from user
myList = []
length = int(input("Enter number of elements : "))
for i in range(0, length):
    value = int(input())
    myList.append(value)

# finding cumulative sum of elements
cumList = []
sumVal = 0
for x in myList:
    sumVal += x
    cumList.append(sumVal) 

# Printing lists 
print("Entered List ", myList)
print("Cumulative sum List ", cumList)

Output:

Enter number of elements : 5
1
7
