Using Python Class Constructors

Class constructors are a fundamental part of object-oriented programming in Python. They allow you to create and properly initialize objects of a given class, making those objects ready to use. Class constructors internally trigger Python’s instantiation process, which runs through two main steps: instance creation and instance initialization. If you want to dive deeper into how Python internally constructs objects and learn how to customize the process, then this video course is for you. In this video course, you’ll: Understand […]

Faster, more memory-efficient Python JSON parsing with msgspec

If you need to process a large JSON file in Python, you want: Make sure you don’t use too much memory, so you don’t crash half-way through. Parse it as quickly as possible. Ideally, make sure the data is actually valid up-front, with the right structure, so you don’t blow up half-way through your analysis. You can put together solutions with multiple libraries, of course. Or, you can use msgspec a new library that offers schemas, fast parsing, and some […]
