How to Use Object-Oriented Programming in Python – Explained With Examples
Object-oriented programming (OOP) is a style of programming that heavily relies on objects. These objects can have attributes and methods. While attributes store data, methods define behavior. Like many other programming languages, Python supports both OOP and functional programming. However, OOP becomes valuable when writing large-sized and complex programs. In...
How to Use DefaultDict in Python
Throughout my time working with datasets in Python, the dictionary has been my most used data structure. It’s versatile and easy to use. Need to count occurrences of a character? Use a dictionary! Want to create a list of soccer players and associated stats? Dictionary! They’re not fool-proof, though. In...
Data Analysis with Python – How I Analyzed My Empire State Building Run-Up Performance
A tower running race is a race that you run up the stairs of a building. These happen around the world. I got the chance to participate in the Empire State Run Up in NYC, 2023 edition. > The Empire State Building Run-Up (ESBRU)—the world’s first and most
How to Install Python on a Mac
Python is the most popular first language for programmers on a Mac. Until recently, the language's lack of standard development tooling, plus competing optional-but-essential development tools, meant a rocky start for Python beginners. To cut through the confusion, I'll show you an up-to-date approach to install Python and set...
How to Use AI to Automate Unit Testing with TestGen-LLM and Cover-Agent
PytIt's important to write clear and efficient unit tests that actually work during the software development process. Unit tests separate out individual code elements and confirm that they work as intended. Effective unit tests not only catch errors but also help you be confident that your code can be...
Applied Data Science with Python – Business Intelligence for Developers [Full Book]
In the high-stakes game of modern business, data isn't just an asset – it's the power you need to outpace your competition. But as a developer, you know that turning raw data into actionable insights can be a frustrating battle. Imagine having the power to effortlessly transform raw data into...
Python Coding Challenges For Beginner Developers – Code and Explanations
Learning Python can be challenging, especially if you're not actually writing enough code. As a beginner, you may go through lessons and tutorials without practicing on your own – and this makes it harder to learn the language. The truth is, you cannot truly learn programming without writing code. It...
How to Write Unit Tests in Python – with Example Test Code
Unit testing is a software testing technique in which individual components or units of a software application are tested independently from the rest of the application. In software development, it's beneficial to break your application into small, isolated units. This approach allows you to write independent tests to check...
How to Fix Common Python Installation Errors on macOS

How to Handle KeyErrors in Python – with Code Examples
When working with dictionaries in Python, you’d often run into KeyError exceptions. Dictionaries are built-in data structures of key value pairs. So you can look up a value—in constant time—using the corresponding key like so: dict[key] returns value. But what if the key doesn't exist in the dictionary...
First-Class Functions, Higher-Order Functions, and Closures in Python – Explained with Code Examples
In modern programming, it's important to understand concepts like first-class functions, higher-order functions, and closures. These ideas help us write flexible and efficient code. They're also the building blocks for many advanced coding techniques. First-class functions and higher-order functions allow us to treat functions as variables, making our code more...
What are Decorators in Python? Explained with Code Examples
In this tutorial, you will learn about Python decorators: what they are, how they work, and when to use them. But before diving into decorators, it's helpful to understand two foundational concepts in Python: first-class functions and closures. First-Class Functions in Python First-class functions mean that functions in Python...
How Does Python's For-Else Loop Construct Work?
Python supports the for-else loop construct that is lesser known but super helpful. If you’ve programmed in Python, you may have used the for loop to iterate over items in iterables such as lists. But for some use cases, using the for loop in conjunction with the else clause can...
