Python 3 Program To Find The Sum of An Array

In this tutorial, you will learn a simple Python program to find the sum of an array. To understand this Python program, you should have an understanding of the following concepts:

• Python programming language
• Variables and datatypes
• Lists
• Functions

We can do this by 2 methods. First, we can calculate the sum of all the elements in the array without using functions. Secondly, we can create a function to add all the elements of an array and then print the sum by calling that function.

Python 3 Program To Find Sum of Array Without Function

Source Code:

Age = [10, 12, 13]       #Inputting Array values. 
theSum = 0               #Definig variable to store the sum of array. 
for i in Age:            #For loop to iterate through the array
 theSum = theSum + i     #Adding array elements. 

print(theSum)            #Outputting the sum of array elements.

Output
