To me, OO Paradigm is not about having a keyword **class** in a language
but the sense of constructing an ensemble of programmed units which makes
sense together. To illustrate, GObject in Gtk+ is as much a first rate OO
implementation as any other. In fact some of the new breed of languages
like Golang do not follow conventional structure of OOP popularized by C++
and Java.

Lets look at integer as an example in Python (int)

class int(object)
   int(x[, base]) -> integer

which is unlike java where int is a "basic" non-class type. An explicit
upgrade to **Integer** class is required to use OOP features. This is done
with sole purpose of machine efficiency.

Python, to me, seems to lean towards reducing development time. To "this
end" simple implementation is used instead of grand frameworks. Data hiding
with public, private, protected is just one of these frames. Yes again I am
critiquing Java.
