The Ultimate Guide to NumPy Package for Scientific Computing in Python

NumPy (pronounced “numb pie”) is one of the most important packages to grasp when you’re starting to learn Python.

The package is known for a very useful data structure called the NumPy array. NumPy also allows Python developers to quickly perform a wide variety of numerical computations.

This tutorial will teach you the fundamentals of NumPy that you can use to build numerical Python applications today.

Table of Contents

You can skip to a specific section of this NumPy tutorial using the table of contents below:

  • Introduction to NumPy
  • NumPy Arrays
  • NumPy Methods and Operations
  • NumPy Indexing and Assignment
  • Final Thoughts & Special Offer

Introduction to NumPy

In this section, we will introduce the NumPy library in Python.

What is NumPy?

NumPy is a Python library for scientific computing. NumPy stand for Numerical Python. Here is the official description of the library from its website:

“NumPy is the fundamental package for scientific computing with Python. It contains among other things:

  • a powerful N-dimensional array object
  • sophisticated (broadcasting) functions
  • tools for integrating C/C++ and Fortran code
  • useful linear algebra, Fourier transform, and random number capabilities

Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide variety of databases.

NumPy is licensed under the BSD license, enabling reuse with few restrictions.”

NumPy is such an important Python library that there are other libraries (including pandas) that are built entirely on NumPy.

The Main Benefit of NumPy

The main benefit of NumPy is that it allows for extremely fast data generation and handling. NumPy has its own built-in data structure called an array which is similar to the normal Python list, but can store and operate on data much more efficiently.

What We Will Learn About NumPy

Advanced Python practitioners will spend much more time working with pandas than they spend working with NumPy. Still, given that pandas is built on NumPy, it is important to understand the most important aspects of the NumPy library.

Over the next several sections, we will cover the following information about the NumPy library:

  • NumPy Arrays
  • NumPy Indexing and Assignment
  • NumPy Methods and Operations

Moving On

Let’s move on to learning about NumPy arrays, the core data structure that every NumPy practitioner must be familiar with.

NumPy Arrays

In this section, we will be learning about NumPy arrays.

What Are NumPy Arrays?

NumPy arrays are the main way to store data using the NumPy library. They are similar to normal lists in Python, but have the advantage of being faster and having more built-in methods.

NumPy arrays are created by calling the array() method from the NumPy library. Within the method, you should pass in a list.

An example of a basic NumPy array is shown below. Note that while I run the import numpy as np statement at the start of this code block, it will be excluded from the other code blocks in this section for brevity’s sake.

import numpy as np

sample_list = [1, 2, 3]

np.array(sample_list)

The last line of that code block will result in an output that looks like this.

array([1,2,3])

The array() wrapper indicates that this is no longer a normal Python list. Instead, it is a NumPy array.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

Difference Between Python Module and Python Package?

Difference between python module and python package?

What’s the difference between a Python module and a Python package?

Module:  It is a simple Python file that contains collections of functions and global variables and has a “.py”  extension file. It’s an executable file and we have something called a “Package” in Python to organize all these modules.

Package:  It is a simple directory which has collections of modules, i.e., a package is a directory of Python modules containing an additional init.py  file. It is the init.py  which maintains the distinction between a package and a directory that contains a bunch of Python scripts. A Package simply is a namespace. A package can also contain sub-packages.

When we import a module or a package, Python creates a corresponding object which is always of type module . This means that the dissimilarity is just at the file system level between module and package.
