Numpy In Python

Introduction to NumPy

•   NumPy is a Python package and it stands for numerical python
•   Fundamental package for numerical computations in Python
•   Supports N-dimensional array objects that can be used for processing multidimensional data
•   Supports different data-types

Array

•   An array is a data structure that stores values of same data type
•   Lists can contain values corresponding to different data types,
•   Arrays in python can only contain values corresponding to same data type


NumPy Array


•   A numpy array is a grid of values, all of the same type, and is indexed by a tuple of 
nonnegative integers
•   The number of dimensions is the rank of the array
•   The shape of an array is a tuple of integers giving the size of the array along each dimension

Creation of array


To create numpy array, we first need to import the numpy package:
