Im very new to python and the object orientated feature doesnt seem to be as
well put together as Java. Can anyone help with this problem?
From one Java head to another I suggest you park what you know about
Java and approach Python with a clear mind.
Python is not Java and Java is not Python, that much has become clear.
Python has actually been around longer than Java and contains many
features you will be familiar with, serialization and introspection to
name but two. The whole 'everything is an object' thing is a bit strange
at first but actually it just means that everything you write is wrapped
up in a component that exposes various standard methods and attributes,
you treat functions as Objects and modules as Objects and even your
classes will automagically sprout new attributes and properties, at
least that's what I've discovered so far.
There is no real enforced concept of information hiding, no binding of
type to variable in fact no concept of typing at all as far as I can
see.
strong typing != static typing
Python is strongly typed, but not statically typed.
> No interfaces and no subtype polymorphism (Python has 'Duck Type'
polymorphism and I haven't really explored all the ramifications of this
yet). It does however have multiple inheritance.

Python doesn't have interfaces as in Java because it isn't statically
typed.
The idea behind Duck Typing is that the actual type doesn't matter; if
it supports the required method(s) and returns the expected type, then
that's good enough!
