Everything is python is not an object. Python uses procedural control structures like if/else/while/for implemented as special keywords. Smalltalk implements those control structures with objects, the Boolean subclasses True and False which have methods ifTrue:ifFalse: and the class BlockContext which implements methods such as whileTrue: and whileFalse:.
Having objects is entirely different from using objects as the basic building block of every abstraction in the language. Objects in Smalltalk are what S-expressions are to Lisp. Python and Ruby just have objects, but those languages aren't built from objects.
