Learn about Numpy broadcasting, a key feature in Python's Numpy library for efficient array operations. Discover the rules, benefits, and examples of Numpy broadcasting.
NumPy
NumPy, short for Numerical Python, is a fundamental library for scientific computing in Python. It supports large multi-dimensional arrays and matrices and a collection of mathematical functions to operate on these arrays efficiently.
NumPy Broadcasting
Numpy broadcasting is a feature that allows element-wise operations on arrays of different shapes. 
Rules of Broadcasting

1. Matching Dimensions

When operating on 2 arrays, numpy compares their shapes , starting from the trailing dimensions. They are compatible if they are equal or one of them is of size 1.

2. Shape Expansion
If the arrays have different shapes, the smaller array is virtually replicated along the dimensions to perform an operation.

Advantages of Broadcasting

1. Saves Memory

2. Eliminates the need for Python Loops
Arithmetic operations are performed automatically with the help of this library and need not to write the Python loops.

In some cases, Broadcasting stretches both arrays to form an output array larger than the initial arrays.
