Python program to find sum of elements in list

In this article, we will learn about the solution and approach to solve the given problem statement.

Problem statement

Given an list as an input, we need to compute the sum of the given list.

Here we have two approaches to consider i.e. using built-in function & using the brute-force approach.

Approach 1 − Using built-in function

Example

 Live Demo

# main
arr = [1,2,3,4,5]
ans = sum(arr)
print ('Sum of the array is ',ans)

Output

15

All the variables & functions are declared in the global scope and are shown below.

Approach 2 − Using brute-force method

Example

 Live Demo

total = 0
# creating a list
list1 =[1,2,3,4,5]
for ele in range(0, len(list1)):
   total = total + list1[ele]
# main
print("Sum of all elements in given list: ", total)

Output

15

All the variables & functions are declared in the global scope and are shown below.

Conclusion

In this article, we learned about the approach to find the sum of the list.
