Boost Your Efficiency with these 6 Numpy Tricks
Motivation
From time to time, when I showed my friends a couple of Numpy methods I use, they find them helpful. So I decided to share these Numpy methods (or tricks) and hope that you will find them helpful as well.

Investigating Numpy and Pandas the Delta Degree of Freedom

Introduction
ddof means the Delta Degrees of Freedom. For example, when you calculate, a standard deviation, the divisor used in calculations is N - ddof, where N represents the number of elements. This ddof is a... | ['Numpy', 'Dof', 'Programming', 'Data Science', 'Pandas'] |
Today I went down a long rabbit hole trying to solve a linting error for a coworker. Our team at ShopRunner uses numpy docstrings, and we check our code with flake8 and flake8-docstrings.
My coworker had written a method that looked like this:

This is a dope docstring.

The Basics
In this section, we will outline a convenient and basic introduction to widely used NumPy modules. Without further delays, let’s get started!
Importing NumPy
Now that NumPy is set up, we can move on to use it. However, before we use it, we have to import it. NumPy can be imported just like any other pytho... | ['Numpy', 'Artificial Intelligence', 'Introduction', 'Data Science', 'Machine Learning'] |
Every time we get data we count standard deviation and average. And no one waits for a pitfall here — but it does for Python numpy library!
This is a nice example from the book “Applied Statistics with R” by David Dalplaz (you can find it at https://daviddalpiaz.github.io/appliedstats/) On page 55 two samples (sampled... | ['Numpy', 'Pandas', 'Python', 'Standard Deviation', 'R Language'] |

When switching between different languages I often find myself writing the code which would work in one technology but is not valid syntax in another. It happens quite often when I try to access the last element of an array in JavaScript. I often try to refer to -1 index, which is perfectly fine in Python, but does not... | ['JavaScript', 'Numpy', 'Python'] |
Computer hardware in today’s world leverages parallel computing for faster computation by making use of SIMD (Single Instruction, Multiple Data) architectures. SIMD is a class of parallel computing in which the logical processors perform a single instruction on multiple data points simultaneously.

Background
To provide some background as to why we care about truncation error, and why we need to use higher-order methods to achieve lower truncation errors
If you are confused about the Taylor Expansion, I’d recommend 3blue1brown’s video on the subject

From calculus, we know that the tr... | ['Numpy', 'Differential Equations', 'Lorenz System', 'Python', 'Runge Kutta'] |
1. Sequences
You may be surprised, as I have stated the 2d-arrays as the topic of the article. Though array to matrix conversion is very wide-spread, so this makes sense. Let’s explore a pair of NumPy native tricks.
For example, for the sequence:
