Python program to find the sum of array

Let’s write a simple python program to find the sum of an array.

It’s very simple to calculate the sum of an array in Python, you just have to use a python function called sum(). 

Here is the example snippet:

#set an array of integers
arr = [10, 20, 30, 40, 50]
#to calculate we just have to use sum()
print ("Sum of the array: ")
print sum(arr)

The output of the above program: 

Sum of the array: 
150

So, just create an array arr = [10,20] of integers in python and pass the array variable to the sum(arr) function to calculate the sum of integers.
