The zip() function in Python programming is a built-in standard function that takes multiple iterables or containers as parameters. An iterable in Python is an object that you can iterate over or step through like a collection. You can use the zip() function to map the same indexes of more than one iterable. Mapping these […]
In this tutorial, we will represent data in a heatmap form using a Python library called seaborn. This library is used to visualize data based on Matplotlib. You will learn what a heatmap is, how to create it, how to change its colors, adjust its font size, and much more, so let’s get started. […]
In this tutorial, you will learn how you can process images in Python using the OpenCV library. OpenCV is a free open source library used in real-time image processing. It’s used to process images, videos, and even live streams, but in this tutorial, we will process images only as a first step. Before getting started, […]
