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
# 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
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.
