Slice and extract a portion of a NumPy array.

Sample Solution:

Python Code:

import numpy as np

# Create a NumPy array
nums = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9])

# Slice and extract a portion of the array
portion = nums[2:6]

# Display the extracted portion
print(portion)

Output:

[3 4 5 6]

Explanation:

Here's a breakdown of the above code:

• We create a NumPy array "nums".
• The slice notation nums[2:6] is used to extract elements from index 2 to 5 (inclusive). Note that the ending index is exclusive in Python slicing.
• The extracted portion is stored in the variable "portion".
• The result is printed, showing the extracted portion of the array.
