# Python: Check the average value of the elements of a given array of numbers is a whole number or not

## Python Basic - 1: Exercise-127 with Solution

Write a Python program to check whether the average value of the elements of a given array of numbers is a whole number or not.

Sample Solution-1:

Python Code:

``````import array as arr
def test(nums):
return sum(nums) % len(nums) == 0
array_num = arr.array('i', [1, 3, 5, 7, 9])
print("Original array:")
for i in range(len(array_num)):
print(array_num[i], end=' ')
print("\nCheck the average value of the elements of the said array is a whole number or not:\n",test(array_num))
array_num = arr.array('i', [2, 4, 2, 6, 4, 8])
print("\nOriginal array:")
for i in range(len(array_num)):
print(array_num[i], end=' ')
print("\nCheck the average value of the elements of the said array is a whole number or not:\n",test(array_num))
``````

Sample Output:

```Original array:
1 3 5 7 9
Check the average value of the elements of the said array is a whole number or not:
True

Original array:
2 4 2 6 4 8
Check the average value of the elements of the said array is a whole number or not:
False
```

Flowchart: Sample Solution-2:

Python Code:

``````import array as arr
def test(nums):
return (sum(nums) / len(nums)) % 1 == 0
array_num = arr.array('i', [1, 3, 5, 7, 9])
print("Original array:")
for i in range(len(array_num)):
print(array_num[i], end=' ')
print("\nCheck the average value of the elements of the said array is a whole number or not:\n",test(array_num))
array_num = arr.array('i', [2, 4, 2, 6, 4, 8])
print("\nOriginal array:")
for i in range(len(array_num)):
print(array_num[i], end=' ')
print("\nCheck the average value of the elements of the said array is a whole number or not:\n",test(array_num))
``````

Sample Output:

```Original array:
1 3 5 7 9
Check the average value of the elements of the said array is a whole number or not:
True

Original array:
2 4 2 6 4 8
Check the average value of the elements of the said array is a whole number or not:
False
```
