## What is NumPy in Python?

**NumPy**is an open source library available in Python, which helps in mathematical, scientific, engineering, and data science programming. It is a very useful library to perform mathematical and statistical operations in Python. It works perfectly for multi-dimensional arrays and matrix multiplication. It is easy to integrate with C/C++ and Fortran.For any scientific project, NumPy is the tool to know. It has been built to work with the N-dimensional array, linear algebra, random number, Fourier transform, etc.

NumPy is a programming language that deals with multi-dimensional arrays and matrices. On top of the arrays and matrices, NumPy supports a large number of mathematical operations. In this part, we will review the essential functions that you need to know for the tutorial on ‘TensorFlow.’

## Why use NumPy?

NumPy is memory efficiency, meaning it can handle the vast amount of data more accessible than any other library. Besides, NumPy is very convenient to work with, especially for matrix multiplication and reshaping. On top of that, NumPy is fast. In fact, TensorFlow and Scikit learn to use NumPy array to compute the matrix multiplication in the back end.

In this Python NumPy Tutorial, we will learn:

- How to Install NumPy
- Python NumPy Array
- numpy.zeros() & numpy.ones() in Python
- numpy.reshape() and numpy.flatten() in Python
- numpy.hstack() and numpy.vstack() in Python
- numpy.asarray() in Python with Example
- np.arange() Function
- numpy.linspace() and numpy.logspace() in Python
- Indexing and Slicing NumPy Arrays
- NumPy Statistical Functions with Example
- Numpy Dot Product Function
- NumPy Matrix Multiplication with np.matmul() Example

## How to Install NumPy

To install NumPy library, please refer our tutorial How to install TensorFlow. NumPy is installed by default with Anaconda.

In remote case, NumPy not installed-

{loadposition sponsored-tool-list-ads}You can install NumPy using Anaconda:

conda install -c anaconda numpy

- In Jupyter Notebook :

import sys !conda install --yes --prefix {sys.prefix} numpy

### Import NumPy and Check Version

The command to import numpy is

import numpy as np

Above code renames the Numpy namespace to np. This permits us to prefix Numpy function, methods, and attributes with ” np ” instead of typing ” numpy.” It is the standard shortcut you will find in the numpy literature

To check your installed version of Numpy use the command

print (np.__version__)

**Output:**1.18.0

## What is Python NumPy Array?

NumPy arrays are a bit like Python lists, but still very much different at the same time. For those of you who are new to the topic, let’s clarify what it exactly is and what it’s good for.

As the name kind of gives away, a NumPy array is a central data structure of the numpy library. The library’s name is actually short for “Numeric Python” or “Numerical Python”.

## Creating a NumPy Array

Simplest way to create an array in Numpy is to use Python List

myPythonList = [1,9,8,3]

To convert python list to a numpy array by using the object np.array.

numpy_array_from_list = np.array(myPythonList)

To display the contents of the list

numpy_array_from_list

**Output:**array([1, 9, 8, 3])
