Python Coding Challange - Question with Answer (01160425)

 

Let's break down this Python code step by step:

import array as arr

• This imports Python's built-in array module and gives it the alias arr.

• The array module provides a space-efficient array (fixed-type) data structure, similar to lists but more efficient for large numeric data.

---

numbers = arr.array('i', [7, 8, -5])

• This creates an array named numbers.

• 'i' is the type code for signed integers (like int), meaning all elements in this array must be integers.

• [7, 8, -5] is the list of integer values used to initialize the array.

---

print(numbers[1])

• This prints the value at index 1 of the array.

• In Python, indexing starts from 0. So:

  • numbers[0] → 7

  • numbers[1] → 8

  • numbers[2] → -5

✅ Output: 8

---

Summary:

• You're creating an integer array [7, 8, -5] and printing the second element (index 1), which is 8.
