Whether you're a beginner or looking to sharpen your skills, this video will guide you step-by-step through essential concepts and practical examples.
What You'll Learn:
✔️ How to create a 2D, 3D, and 4D array in Python with NumPy
✔️ Key properties like ndim, shape, size, and dtype explained
✔️ How to calculate the total size and understand array dimensions
✔️ Practical use of 2D, 3D, and 4D arrays in data science, machine learning, and scientific computing
Why Use NumPy for Arrays?
High Performance: NumPy arrays are faster and more memory-efficient than traditional Python lists.
Advanced Features: Supports multi-dimensional arrays for complex operations.
Data Science Ready: Essential for handling large datasets in AI, machine learning, and deep learning projects.
Code Demonstrated in the Video:
python
Copy code
import numpy as np
arr = np.array([[[[1, 2], [3, 4]], [[5, 6], [7, 8]]],
[[[9, 10], [11, 12]], [[13, 14], [15, 16]]]])
print("Array is of type: ", type(arr))
print("No. of dimensions: ", arr.ndim)
print("Shape of array: ", arr.shape)
print("Size of array: ", arr.size)
print("Array stores elements of type: ", arr.dtype)
