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 […]

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 […]
