Numpy Library Introduction

Numpy is a fundamental package for scientific computing with Python. It provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays efficiently.

Key Features

  • Arrays and Matrix Operations: Numpy provides powerful tools for handling arrays and matrices, which are essential for numerical computations.
  • Vectorization: Functions operate element-wise on vectors and matrices, which can lead to significant performance improvements.
  • Integration with Python: Numpy seamlessly integrates with Python's syntax and data types, making it easy to use within Python scripts and applications.

Basic Usage

Here's a simple example of how to use Numpy:

import numpy as np


arr = np.array([1, 2, 3, 4])

# Element-wise addition
result = arr + 5

print(result)
