In this article, we will learn about the solution to the problem statement given below.

**Problem statement **− We are given a list, we need to create a list with the cumulative sum.

Now let’s observe the solution in the implementation below −

# cumulative sum def Cumulative(l): new = [] cumsum = 0 for element in l: cumsum += element new.append(cumsum) return new # Driver Code lists = [10, 20, 30, 40, 50] print ("New list:",Cumulative(lists))

New list: [10, 30, 60, 100, 150]

All the variables are declared in the local scope and their references are seen in the figure above.

In this article, we have learned about how we can make a Python program to find the Cumulative sum of a list.
