Python Program to find sum of array
Given an array of integers, find the sum of its elements.
Examples :
Input : arr[] = {1, 2, 3}
Output : 6
1 + 2 + 3 = 6
Input : arr[] = {15, 12, 13, 10}
Output : 50
Method 1:
# Python 3 code to find sum # of elements in given array def _sum(arr): # initialize a variable # to store the sum # while iterating through # the array later sum=0 # iterate through the array # and add each element to the sum variable # one at a time for i in arr: sum = sum + i return(sum) # driver function arr=[] # input values to list arr = [12, 3, 4, 15] # calculating length of array n = len(arr) ans = _sum(arr) # display sum print ('Sum of the array is ', ans) # This code is contributed by Himanshu Ranjan |
Output:
Sum of the array is 34
Method 2:
# Python 3 code to find sum # of elements in given array # driver function arr = [] # input values to list arr = [12, 3, 4, 15] # sum() is an inbuilt function in python that adds # all the elements in list,set and tuples and returns # the value ans = sum(arr) # display sum print ('Sum of the array is ',ans) # This code is contributed by Dhananjay Patil |
Output:
Sum of the array is 34
