How to Find Sum of Elements in List in Python

In this tutorial, we will program 'How to Find the Sum of Elements in a List in Python'. We will learn how to get the actual sum of the elements in a list. The objective is to enable you to efficiently get the sum of the list. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for getting the sum in a list. I will do my best to provide you with the easiest way for getting the the sum. So, let's start with the coding.

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

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.
  1. ret = False
  4. while True:
  5. print("\n================== Find Sum of Elements in List in Python ==================\n\n")
  7. total = 0
  10. my_list = [8, 5, 15, 12, 9, 11]
  12. print("My List: ", my_list)
  13. print("\n")
  15. for ele in range(0, len(my_list)):
  16. total = total + my_list[ele]
  18. print("Sum of all elements in given list: ", total)
  20. opt = input("\nDo you want to try again?(yes/no): ")
  22. if opt.lower() == 'yes':
  23. ret=False
  24. elif opt.lower() == 'no':
  25. ret=True
  26. print("Exiting program....")
  28. else:
  29. print("Please enter yes/no:")
  30. break
  32. if ret == False:
  33. continue

This Python script calculates the sum of all elements in a predefined list my_list. It initializes a variable total to zero and iterates over each element in the list, adding each element to total. After calculating the sum, it prints the list and the total sum of its elements. The script then asks the user if they want to try again or exit the program.
