On: Don't Distract New Programmers with OOP

[possibilistic]

If you're tying to develop interfaces in Python, I would argue you're using the language from the wrong standpoint.

Every language has a design goal. Python doesn't care about interface contracts. The "one correct way" is the contract.

With these languages it always seems like first came the language, and then its users tried really hard to make sense of it. So now apparently enforcing contracts is not important anymore. "Let's just code!" - sigh

[possibilistic → jafaku]

If you want to enforce contracts, pick a language that encourages it. There are many to choose from. Plenty of people are doing just fine in Python without this.

It's almost an entirely distinct problem domain. Besides, what would a contract be in a dynamically typed language?

I don't think these features are bad, but they're not appropriate everywhere.

Yeah don't worry, I'm not gonna use Python.

Being dynamic has nothing to do with this. See: Clojure, PHP, etc. They have contracts.

Of course things might not be appropriate everywhere. But with Python/Ruby you don't have a choice, they just lack these features.
