Something new I came across while storing data stream to Python class is Dataclass! Let’s dive in. dataclass is a decorator imported from dataclasses module and generates special methods such as __init__ , __repr__ to user-defined classes. Let’s see an example: On running the file, we get: Generated special…

If you have come across application directories in python, you must have seen directories converted to packages with __init__.py file. The basic function of the file is to initialize a directory just like in class where we use __init__ method to initialize a class. That was my understanding, until recently…

Logging in Python codebase had been pretty mysterious to me while working in large codebases. I had not set the configuration nor did I look at the configurations in detail but used logging functionality often for debugging. Later did some extension on an existing logging configuration for a utility program…

Came across functions in Python that had inline annotation of arguments passed to the function and annotated return type as well. It looked so similar to Dafny and Lustre language that I’d learned in Formal Methods class in graduate school. Was a bit surprised that their exist such a feature…

In this article we’ll learn about Dockerfile and create a simple container based on it! When I first saw a Docker logo 🐳 few years ago, timeline wise it was after completing graduate school, thought it was cute and clever. It must have been a buzz word then. Tried two…

We now know what a generator is, how to send values to a generator, and how to close a generator. This article is looking at how we can have two-way communications using caller, sub-generator using yield from , yield and send. We know how we can generate and consume values…

In this article we’ll see how we can close generators and throw exceptions to generators. If you want to know what is a generator, sending values to generator, you can look at part I and part II of the yield series respectively. Let’s take an example of reading a file…

Part II: A guide on passing values to generators using the “yield” expression in Python. — This part of the yield article is about sending value to generators. We have talked about yield , generators, how generators are used as coroutines, and states of a generator in part I of the yield article. Let’s check out how we can pass value to generators. yield is an…

yield keyword looked pretty mysterious when occasionally encountered. Here we are unpacking what yield does by looking at how generator uses yield to get values or return back control to a caller. We are also looking at different states of a generator. Let’s dive in. Generator function: A function that…
