Write a Python program to calculate the average of an array or Numpy array of elements. The Python Numpy module has the sum and average methods to find the sum and average of array items.
import numpy as np arr = np.array([10, 20, 40, 60, 80, 100]) total = arr.sum() avg = np.average(arr) print('\nThe Sum Of Array Elements = ', total) print('\nThe Average Of Array Elements = ', avg)

This python program uses for loop to iterate Numpy Array items and calculates the sum and average of all elements.
import numpy as np arr = np.array([14, 25, 35, 67, 89, 11, 99]) total = 0 for i in range(len(arr)): total = total + arr[i] avg = total / len(arr) print('\nThe Sum Of Array Elements = ', total) print('\nThe Average Of Array Elements = ', avg)
The Sum Of Array Elements = 340
The Average Of Array Elements = 48.57142857142857
Python program to calculate the average of an array using a while loop
import numpy as np arr = np.random.randint(10, 150, size = 11) print('The Random Array Genegrated') print(arr) total = 0 i = 0 while i < len(arr): total = total + arr[i] i = i + 1 avg = total / len(arr) print('\nThe Sum Of Array Elements = ', total) print('\nThe Average Of Array Elements = ', avg)
The Random Array Genegrated
[123 91 119 131 45 121 48 53 44 60 82]
The Sum Of Array Elements = 917
The Average Of Array Elements = 83.36363636363636
This Python example allows to enter array elements and finds the sum and average of all array items.
import numpy as np arrlist = [] Number = int(input("Total Array Elements to enter = ")) for i in range(1, Number + 1): value = int(input("Please enter the %d Array Value = " %i)) arrlist.append(value) arr = np.array(arrlist) total = 0 for i in range(len(arr)): total = total + arr[i] avg = total / len(arr) print('\nThe Sum Of Array Elements = ', total) print('\nThe Average Of Array Elements = ', avg)
Total Array Elements to enter = 7
Please enter the 1 Array Value = 22
Please enter the 2 Array Value = 44
Please enter the 3 Array Value = 66
Please enter the 4 Array Value = 88
Please enter the 5 Array Value = 99
Please enter the 6 Array Value = 122
Please enter the 7 Array Value = 154
The Sum Of Array Elements = 595
The Average Of Array Elements = 85.0
