When developing web applications - we routinelly access resources hosted on a server. Asking for, sending, or performing other operations on resources is accomplished through HTTP requests. These requests are sent from the client to a host on a server. When making HTTP request, the client employs a URL (Uniform...

A dictionary in Python is a collection of items that stores data as key-value pairs. In Python 3.7 and later versions, dictionaries are sorted by the order of item insertion. In earlier versions, they were unordered. In this article, we'll take a look at how we can sort a...

To work with stored data, file handling becomes the core knowledge of every professional Python programmer. Right from its earliest release, both reading and writing data to files are built-in Python features. In comparison to other programming languages like C or Java, it is pretty simple and only requires a...

Python programmers intensively use arrays, lists, and dictionaries as serialized data structures. Storing these data structures persistently requires either a file or a database to properly work. In this article, we'll take a look at how to write a list to file, and how to read that list back into...
There are usually multiple ways to solve the problem using a computer program. For instance, there are several ways to sort items in an array - you can use merge sort, bubble sort, insertion sort, and so on. All of these algorithms have their own pros and cons and the...

The K-nearest Neighbors (KNN) algorithm is a type of supervised machine learning algorithm used for classification, regression as well as outlier detection. It is extremely easy to implement in its most basic form but can perform fairly complex tasks. It is a lazy learning algorithm since it doesn't have a...

When working with APIs we oftentimes want to send data to the server for processing. For example, if we have a list of to-dos and want to add to it, perhaps through a form submission, we use POST HTTP requests to send a request with a payload for processing and...
As pointed out in a previous article that deals with reading data from files, file handling is essential knowledge of every professional and hobbyist Python programmer. This feature is a core part of the Python language, and no extra module needs to be loaded to do it properly. In this...
K-Means clustering is one of the most widely used unsupervised machine learning algorithms that form clusters of data based on the similarity between data instances. In this guide, we will first take a look at a simple example to understand how the K-Means algorithm works before implementing it using Scikit-Learn....
