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)
