Python

After writing nearly 20 articles just about Python, I’ve decided to take some time to reflect on what I’ve learned. For instance, I recently wrote a compilation article which includes 70+ Python code snippets. Now, I’ve put together a list of some of the coolest Python programming language features. Coolest Python Features List And without further ado, let’s take a ...

One concept that threw me for a loop when I first picked up Python was checking if a string contains a substring. After all, in my first language, Java, the task involved calling a method like indexOf() or contains(). Luckily, Python has an even cleaner syntax, and we’ll cover that today. To summarize, we can check if a string contains ...

Lately, I’ve been thinking about new Python topics to write about, so I took to Google. When I searched “Python how to”, “Python how to add to a list” popped up first. Since this must be a popular search term, I decided it was worth an article. In other words, today we’ll learn how to add an item to a ...

Welcome to yet another Python tutorial. Today, we’re taking a look at dictionaries and how we can perform a reverse dictionary lookup. In words, how do we get a key from a dictionary given a value? As it turns out, there are three main solutions. First, we could try explicitly looping over the dictionary using something like my_dict.items(). Alternatively, we could ...

If you’ve been following me for any amount of time, you know that I regularly publish Python code snippets for everyday problems. Well, I figured I’d finally aggregate all those responses in one massive article with links to all those resources. Everyday Problems In this section, we’ll take a look at various common scenarios that arise and how to solve ...

A lot of the articles in this series take advantage of a feature of Python which allows us to performance test our code, and I finally wanted to get around to explaining how it works and how to use it. In this article, I cover three main techniques: brute force, timeit, and cProfile. Personally, I performance test my code with ...

Fantasy Football is a nerdy game. By saying that, there is no way you can win the championship without studying it. That’s how web scraping comes in handy. In this tutorial, you will learn how to build a web scraping tool to accomplish the job. You can now curate valuable data automatically into one spreadsheet promptly. Rather than looking up ...

The standard deviation allows you to measure how spread out numbers in a data set are. Large values of standard deviations show that elements in a data set are spread further apart from their mean value. In this tutorial, we will calculate the standard deviation using Python Small standard deviations show that items don’t deviate significantly from the mean value ...

If you haven’t heard, Python 3.8 features a rather controversial new operator called the walrus operator. In this article, I’ll share some of my first impressions as well as the views from all sides. Feel free to share some of your thoughts as well in the comments. Understanding the Walrus Operator Recently, I was browsing dev.to, and I found a ...
