Matplotlib: Draw Vertical Lines on Plot

Introduction Matplotlib is one of the most widely used data visualization libraries in Python. Much of Matplotlib’s popularity comes from its customization options – you can tweak just about any element from its hierarchy of objects. In this tutorial, we’ll take a look at how to draw a vertical line on a Matplotlib plot, that allows us to mark and highlight certain regions of the plot, without zooming or changing the axis range. Creating a Plot Let’s first create a […]

Validating and Formatting Phone Numbers in Python with phonenumbers

Introduction Validating phone numbers can be a very challenging task. The format of a phone number can vary from one country to another. Heck, it can also vary within the same country! Some countries share the same country code, while some other countries use more than one country code. According to an example from the Google’s libphonenumber GitHub repository, USA, Canada, and Caribbean islands, all share the same country code (+1). On the other hand, it is possible to call […]

Python AI: How to Build a Neural Network & Make Predictions

If you’re just starting out in the artificial intelligence (AI) world, then Python is a great language to learn since most of the tools are built using it. Deep learning is a technique used to make predictions using data, and it heavily relies on neural networks. Today, you’ll learn how to build a neural network from scratch. In a production setting, you would use a deep learning framework like TensorFlow or PyTorch instead of building your own neural network. That […]

Python: How to Print Without Newline or Space

Introduction The print() function in Python appends a newline to the output when displayed on the tty (teletypewriter A.K.A the terminal). When you don’t want your message displayed with newlines or with spaces, how can you change the behavior of print()? This can easily be achieved by altering the default values of the sep and end parameters of the print() function. Printing Without a Newline Until Python version 2.x, print was a reserved keyword that acts as a special statement. […]

How to Split a List Into Even Chunks in Python

Introduction Splitting strings and lists are common programming activities in Python and other languages. Sometimes we have to split our data in peculiar ways, but more commonly – into even chunks. The language does not have a built-in function to do this and in this tutorial, we’ll take a look at how to split a list into even chunks in Python. For most cases, you can get by using generators: def chunk_using_generators(lst, n): for i in range(0, len(lst), n): yield […]
