Decisions are usually based on the sample mean, which is very sensitive to outliers and can dramatically change the value. So, it is crucial to manage outliers
Webhooks run a large portion of the "magic" that happens between applications. They are sometimes called reverse APIs, callbacks, and even notifications. Many services, such as SendGrid, Stripe, Slack, and GitHub use events to send webhooks as part of their API. This allows your application to listen for events and perform actions when they happen.

While working on a recent project, I realized that heavy processes for python like scrapping could be made easier though python's multiprocessing library. The documentation and community engaging in multiprocessing is fairly sparse, so I wanted to share some of my learnings through an example project of scrapping the PokéAPI. Below I wrote a bit of code that pulls all of the available pokémon while minding the API's 100 calls per 60 second limits. You'll see that the iteration is fairly slow as there are 964 pokémon the API returns.
A stack is a data structure in which items are added and removed from the same point. It's kind of a one way storage system. Also known as LIFO data structure.
In my free time, I am attempting to build my own smart home devices. One feature they will need is speech recognition. While I am not certain yet as to how exactly I want to implement that feature, I thought it would be interesting to dive in and explore different options. The first I wanted to try was the SpeechRecognition library.
Hello guys, If you follow my blog regularly, or read my articles here on HackerNoon, then you may be wondering why am I writing an article to tell people to learn Python? Didn’t I ask you to prefer Java over Python a couple of years ago?
Object-relational mappers (ORMs) are often used in Python programming when one needs to develop an application that works with databases. Examples of Python ORMs are SQLAlchemy, Peewee, Pony-ORM and Django. When choosing an ORM, performance plays a crucial role. But how are these toolsets compared? ORM performance benchmarks offer a measure of clarity but leave considerable room for improvement. I examine and extend the qualitative ORM benchmark to develop a stronger metric.
Python is a known modular language which imports many useful operations from its standard library. Of course, it isn’t possible to program Python without using it. It has become an excellent alternative for many programmers because it is an open source program which was developed under an OSI license. You can download, install and run it on any computer without any charge. It is available in various builds and supports around 21 different operating systems making it have universal appeal.

Images. That's it. Images. As a point of practicality, take a fashion designer (as a forum member vividly described to me at one point). You are given an image or have an image at your disposal that simply tickles your curiosity and want to incorporate it in one of your new lines. Let's swerve a little into the genetics section. Given a petri dish image for instance, with pigmented bacteria or similar organisms, and you would like to find the abundance of that organism or organisms in this specific image. Get the gist?
Python is one of the most popular programming languages. It is easy to pick up and begin with the basics. It is a general-purpose language and can be used for more a lot of things other than just web development. To get a job, you need to go beyond learning just the basics and have a solid understanding of the complexities involved in the language.
Oh! If all your code worked as it was supposed to.. Of-course you just made a tiny change and the whole system came crashing down! The existing system seems almost alive, and resists any code change by crashing! Quite often, developers declare a truce in the form of a 'code-freeze'! After a deep breath (perhaps several weeks..) the code-freeze is lifted, and the battle is renewed.
There are many articles on analyzing Spotify data and many applications as well. Some are a one-time analysis on individual's music library and some are an app for a specific purpose. This app is different in that it does not do one thing. It is meant to grow and provide a place to add more analysis. This article is about how the audio features time series was created.
