NumPy Python Programming and Project Development using NumPy

NumPy stands for Numerical Python and it is a core scientific computing library in Python. NumPy provides efficient multi-dimensional array objects and various operations to work with these array objects.

NumPy is a Python library used for working with arrays. It also has functions for working in domain of linear algebra, fourier transform, and matrices. NumPy was created in 2005 by Travis Oliphant. It is an open source project and you can use it freely. NumPy is written partially in Python, but most of the parts that require fast computation are written in C or C++.

Purpose of using NumPy

In Python we have lists that serve the purpose of arrays, but they are slow to process. NumPy aims to provide an array object that is up to 50x faster than traditional Python lists. The array object in NumPy is called ndarray, it provides a lot of supporting functions that make working with ndarray very easy. Arrays are very frequently used in data science, where speed and resources are very important.

NumPy arrays are stored at one continuous place in memory unlike lists, so processes can access and manipulate them very efficiently. This behavior is called locality of reference in computer science. This is the main reason why NumPy is faster than lists. Also it is optimized to work with latest CPU architectures.

NumPy is essentially a library consisting of multidimensional array objects and a collection of routines for processing those arrays. Using NumPy, mathematical and logical operations on arrays can be performed.

NumPy lies at the core of a rich ecosystem of data science libraries. A typical exploratory data science workflow might look like:

• Extract, Transform, Load: Pandas, Intake, PyJanitor

• Exploratory analysis: Jupyter, Seaborn, Matplotlib, Altair

• Model and evaluate: scikit-learn, statsmodels, PyMC3, spaCy

• Report in a dashboard: Dash, Panel, Voila

Features of NumPy

1. POWERFUL N-DIMENSIONAL ARRAYS

   • Fast and versatile, the NumPy vectorization, indexing, and broadcasting concepts are the de-facto standards of array computing today.

2. NUMERICAL COMPUTING TOOLS

   • NumPy offers comprehensive mathematical functions, random number generators, linear algebra routines, Fourier transforms, and more.

3. INTEROPERABLE

   • NumPy supports a wide range of hardware and computing platforms, and plays well with distributed, GPU, and sparse array libraries.

4. PERFORMANT

   • The core of NumPy is well-optimized C code. Enjoy the flexibility of Python with the speed of compiled code.

5. EASY TO USE

   • NumPy’s high level syntax makes it accessible and productive for programmers from any background or experience level.

6. OPEN SOURCE

   • Distributed under a liberal BSD license, NumPy is developed and maintained publicly on GitHub by a vibrant, responsive, and diverse community.

Using NumPy, a developer can perform the following operations −

• Mathematical and logical operations on arrays.

• Fourier transforms and routines for shape manipulation.

• Operations related to linear algebra. NumPy has in-built functions for linear algebra and random number generation.
