there are no private variables in python. Does anyone know why python
classes have no private variables and why python's OOPS concept are a lot
different from other programming languages?
Meh! Weak arguments, strongly made.

You will find python having superior constructs eg. metaclasses etc. if you
were comparing Python OOP to C++/Java.
Superior constructs implemented inferiorly. Meteclasses are much^3 more
powerful in Groovy, Ruby and SmallTalk (where some would claim Python
borrowed them from; but that's just not true.) Trust me, I spent almost a
week trying to wrap my head around this before I figured out that Python
Metaclasses are just Class Decorators done differently (read- requiring you

I'd suggest you keep an open mind and go with what the language/platform
provides you. Python is one of those 'get stuff done' kind of languages and
has a sweet spot, but OO isn't quite all in that spot. There is some
overlap, but it can be hard to find.
