Python Coding Challange - Question with Answer (01030525)

 

Explanation:

1. import array as arr
   This imports Python's built-in array module and gives it the nickname arr.

2. e = arr.array('i', [7, 14, 21, 28])
   This creates an array named e with integer type 'i'.
   The array contains 4 elements:
   e = [7, 14, 21, 28]

3. e[:3]
   This is slicing the array. It selects the first 3 elements (index 0 to 2):
   [7, 14, 21]

4. sum(e[:3])
   This calculates the sum of the sliced array:
   7 + 14 + 21 = 42

5. print(...)
   The output will be:
   42

 Final Output:

42
