NumPy Tutorial for Beginners | Joining & Splitting Arrays Explained with Examples

Learn how to join and split NumPy arrays in this beginner-friendly Python tutorial! 🚀 In this video, we’ll learn how to combine multiple NumPy arrays and split a single array into smaller arrays. These operations are very useful when working with datasets and are commonly used in **Data Science, Machine Learning, and Python programming**. 📚 Topics Covered What is joining in NumPy? Joining arrays with *`concatenate()`* Joining arrays with *`stack()`* Understanding *`axis`* Horizontal stacking with *`hstack()`* Vertical stacking with *`vstack()`* Difference between `stack()`, `hstack()`, and `vstack()` What is splitting in NumPy? Splitting arrays with *`split()`* Splitting arrays with *`array_split()`* Difference between `split()` and `array_split()` Splitting 2D arrays Splitting arrays using *`axis`* Practical examples of joining and splitting arrays 💻 Example Here's a simple example of joining two NumPy arrays: ```python import numpy as np arr1 = np.array([1, 2, 3]) arr2 = np.array([4, 5, 6]) result = np.concatenate((arr1, arr2)) print(result) ``` Output: ```text [1 2 3 4 5 6] ``` And here's an example of splitting an array: ```python arr = np.array([1, 2, 3, 4, 5, 6]) result = np.array_split(arr, 3) print(result) ``` Output: ```text [array([1, 2]), array([3, 4]), array([5, 6])] ``` 🎯 Why Learn Joining & Splitting? Joining and splitting arrays are important skills when working with **large datasets**. They help you organize, combine, divide, and prepare data efficiently before performing further analysis or building Machine Learning models. 🎓 Who Is This Video For?
