In this blog, I'm going to tell how to find sum of array in python.
Example:
Input : arr[] = {12, 3, 4, 15}
Output : 34
Method 1:
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)
Output:
Sum of the array is 34
Method 2:
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)
Output:
Sum of the array is 34
