python numpy array concatenate

NumPy is a powerful library in Python for numerical operations, particularly when working with arrays. One common operation is concatenating arrays, which means combining two or more arrays to form a new one. In this tutorial, we will explore the various ways to concatenate NumPy arrays with code examples.
Let's start by concatenating two 1D arrays:
Output:
Concatenating 2D arrays requires specifying the axis along which the concatenation will occur. Let's concatenate two 2D arrays along rows and columns:
Output:
You can concatenate arrays along a specific axis using the axis parameter. Here's an example with 3D arrays:
Output:
Output:
In this tutorial, we covered the basics of concatenating NumPy arrays. Understanding these techniques is crucial for manipulating and combining arrays in scientific computing and data analysis using Python. Experiment with different examples to solidify your understanding of array concatenation in NumPy.
