Python Coding Challenge - Question with Answer (ID -311225)

 Explanation:

1. Importing NumPy

import numpy as np

Imports the NumPy library.

np is an alias used to access NumPy functions easily.

2. Creating a NumPy Array

x = np.array([1, 3, 5])

Creates a NumPy array named x.

x contains three elements: 1, 3, and 5.

3. Initializing a Variable

y = 1

Initializes variable y with value 1.

We use 1 because this variable will store a product (multiplication), and 1 is the neutral element for multiplication.

4. Looping Through the Array

for i in range(len(x)):

len(x) gives the length of the array → 3.

The loop runs with i = 0, 1, 2.

i is used as the index to access elements of x.

5. Multiplying Each Element

    y *= x[i]

Multiplies the current value of y by the element at index i.

Step-by-step:

i = 0 → y = 1 × x[0] = 1 × 1 = 1

i = 1 → y = 1 × x[1] = 1 × 3 = 3

i = 2 → y = 3 × x[2] = 3 × 5 = 15

6. Printing the Result

print(y)

Prints the final value of y.

Final Output

15
