How to Find Cumulative Sum of a List in Python
In this tutorial, we’ll learn how to program “How to Find the Cumulative Sum of a List in Python.” The objective is to safely and efficiently find the cumulative sum of a list. This tutorial will guide you through the process step by step, ensuring that the result is accurate. So, let’s get started!
This topic is straightforward to understand. Just follow the instructions I provide, and you’ll complete it with ease. The program I’ll demonstrate will illustrate the proper way to find the cumulative sum of a list. So, let’s dive into the coding process!
Getting Started:
First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.
Creating Main Function
This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.- def cumulative_generator(l):
- total = 0
- for num in l:
- total += num
- yield total
- while True:
- print("\n================= Find Cumulative Sum of a List =================\n\n")
- l = [4, 5, 7, 9, 12]
- print("Current List: ", l)
- cumulative_sum = list(cumulative_generator(l))
- print("Sum: ", cumulative_sum)
- opt = input("\nDo you want to try again?(yes/no): ")
- if opt.lower() == 'yes':
- ret=False
- elif opt.lower() == 'no':
- ret=True
- print("Exiting program....")
- else:
- print("Please enter yes/no:")
- break
- if ret == False:
- continue
This program calculates the cumulative sum of a list of numbers using a generator function called cumulative_generator(). It iterates through the list, adding each number to a running total and yields the cumulative sums one by one. The results are collected in a list and displayed. The program repeats until the user chooses to exit.
Output:
There you have it we successfully created How to Find Cumulative Sum of a List in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
