What is __init__ in Python?

Reading over other people’s Python code, beginners often stumble over the __init__(self) method. What’s its purpose? This article answers this question once and for all. So what’s __init__(self) in Python? The __init__ method is the constructor of a class. The constructor method initializes the attributes of a classes’ instance. Say, you define a class Dog with instance attribute color. When creating a specific Dog instance, the constructor method is where you set its color. While this answers the question, if you’ve got any ambition in becoming a professional Python coder,…

When to Use a List Comprehension in Python

Python is famous for allowing you to write code that’s elegant, easy to write, and almost as easy to read as plain English. One of the language’s most distinctive features is the list comprehension, which you can use to create powerful functionality within a single line of code. However, many developers struggle to fully leverage the more advanced features of a list comprehension in Python. Some programmers even use them too much, which can lead to code that’s less efficient and harder to read. By the end of this tutorial,…

Erik Marsja: How to Handle Coroutines with asyncio in Python

The post How to Handle Coroutines with asyncio in Python appeared first on Erik Marsja. When a program becomes very long and complex, it is convenient to divide it into subroutines, each of which implements a specific task. However, subroutines cannot be executed independently, but only at the request of the main program, which is responsible for coordinating the use of subroutines. In this post, we introduce a generalization of the concept of subroutines, known as coroutines: just like subroutines, coroutines compute a single computational step, but unlike subroutines, there…

Real Python: Python REST APIs With Flask, Connexion, and SQLAlchemy – Part 4

In Part 3 of this series, you added relationships to the REST API and to the database that supports it. This gave you a powerful tool you can use to build interesting programs that send persistent data, as well as the relationships between that data, to a database system. Having a REST API gives you the ability to create a Single-Page Application (SPA) with HTML, CSS, and JavaScript. This is a good starting point before you make the jump to more powerful front-end frameworks, like Angular or React. In this…

Reuven Lerner: Early-bird pricing for Weekly Python Exercise ends tomorrow

My native language is English: I grew up speaking it at home and school, and it’s my preference when reading, writing, and speaking. I studied in US schools through 12 grade, and then got both a bachelor’s degree and a PhD at American universities.  I’ve been writing for years, including 20 years as a columnist at Linux Journal. Am I fluent in English? Yes, I’d say so.  And yet, I’m always reading tidbits about the history of English, how to speak more clearly, and how sharpen the language I use…
