I've been focusing on coding in the data space lately, and I'm trying to understand how interfaces work in Python. I've read about them and the theory behind them, but honestly, they seem kind of pointless in actual practice. Most of the functions I write don't seem to benefit from using interfaces. Can anyone share some good examples or use cases for interfaces in Python that might help clarify their value?

Interfaces are actually pretty useful, especially for dependency injection. Think of it like this: if you have a database interface that lets your code query data, you could create different implementations for different databases like Postgres and SQLite. This way, you can easily use the SQLite version in your tests without messing with your main code. It keeps things neat and manageable!
Don't sweat it if OOP isn't vibing with your Python projects. Sometimes plain functions and modules work just as well. OOP shines when you're managing state or need specific behaviors across various situations. But if you're just processing data, don't force it; there's often simpler solutions without getting too deep into OOP.
That makes sense! I usually feel like I can write more straightforward code without all the OOP complexity. Maybe I’m overcomplicating things.
