Slicing and extracting a portion of a NumPy array
Python Pandas Numpy: Exercise-23 with Solution
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.
