misplaced sense that you have to look at every value. Why write code
with
unnecessary guard values and temporary variables out of a misplaced

that functions must only have one exit?
Object Oriented programming is all about encapsulating human concepts
in a way that makes sense to human beings. Make no mistake, it is
NEVER the case that a software system is written for any other reason
than to serve human beings. OO is more than just the mechanics of
writing code, it's a state of mind.
I must admit I have no idea how we went from discussing Single Exit
functions to the One True Purpose of Object Oriented Programming; are
you saying that SE is one of the basic tenets of OO?
It's my fault, I get carried away sometimes. Maintainable code is one of
the basic tenets of OO, it all seems so clear to me and I get frustrated
when I think that others don't see the 'beauty' ... but then I come to
my senses and realise that there is always another way to do things.
Python looks like an interesting language and I will certainly spend
time getting to know it but at the moment it seems to me that calling
it an Object Oriented language is just plain misleading.
Since *everything* in Python is an object, how can you /not/ call it an
OO language?
Obviously I can't. I can't make a call as I haven't studied the language
yet. I just can't get my head around duck typing at the moment as it is
just so ... different.
Sure, you don't have to use everything as an object --
plain functions exist -- kinda ;) Even functions live in some namespace:
len() lives in __builtin__, any top level function lives in its module,
etc. Oh, and namespaces are objects.
It seems to me that Python is more about providing tools, and then
staying out of your way.
That works for me. Maybe it will work for you, too.
I hope so and thank you for being so calm and reasonable in your response.
