I agree. I came to Python in 2000, after Perl (1996-1998), PHP (1999), Matlab (1992-1996), C++ (1990), Fortran (1989), C (1988), Pascal (1988), Assembly (1984-86) and Basic (1981-83). After all those, I found Python, as the saying goes, really does "fit your brain" [1]. Since discovering Python 18 years ago, I have looked at Haskell, successfully avoided Java, and promised myself to "one day" do more JS. Still, Pytho…

> "Python fits your brain" For me, I find using python is like touching both data and code with my hands. As much as it's trendy to bash Object Oriented languages, the way python allows to lookup all variables and method on a class or an object makes it like using your hands: dir(MyClass) help(MyClass) dir(my_object) help(my_object) etc...

Right, they're even better than Interfaces: both a contract and a partial implementation. No need for an "Interface" when you've got ABCs.

I see what you mean, but to me abstract classes are distinct from interfaces. Abstract class answers the question "what an object is?", whereas an interface is about what the object can do.

In what strongly typed language does the division of two integers result in a float?

Many languages are not strongly typed (where "strongly typed" means "variables must be predeclared with their types (though they may be inferred)"). If your only experience is with strongly-typed languages, then MANY things about Python will be different, because Python is one of many languages that is not strongly typed. For example, in Scheme (a Lisp), a division (/) presented with exact input values and a non-zero…

Oh, I see. I use spaces and vim (I do, but who cares). Let's start a flamewar. /s Every time I think about tabs/spaces, I think about that episode in Silicon Valley [1]. Hilariously accurate, I have the exact same feeling when somebody uses the mouse to copy something or navigate. The cringe makes me feel alive (I guess this is the ultimate reason for those flamewars. And neurotic tendencies, of course). [1]: https:/…

The distinction between what an object is and what an object can do is an artifact of bad object modelling (specifically, single inheritance OOP.) Any “can do” set has an exactly corresponding “is a thing that can do” set, so there is no logical need for different constructs to model “is” sets and “can do” sets.
