Question about Objects

[campbell95]

I've been hacking visual basic for several years and understand the basic
concepts of OOP. That said, I'm stumped here with the Python Class.

Here is the Class...

>class Test:
> def __init__(self, something):
> self.something = something
>
> def getSomething(se lf):
> return self.something[/color]

This is what I get when I test it. Why does <getSomething > not return the
value of <something>? is obvious that <something> has a value. I fear this
is a simple oversight but I've racked my brain for hours looking at online
doc's and examples. Thanks for any help!!

you need to actually call the method: x.getSomething( )

Remember, this isn't VB: you can't leave the parens off when calling a method.
There's no difference between subs and functions in Python, and you must
include the parens if you want to _call_ the function and get the value.
Otherwise you get the function.

It makes sense, it just that you're used to the peculiar MS-way of doing
things. Your mind will heal, don't worry. ;-)

You're welcome !-) And yes, this is probably one of the friendliest
places on usenet (thanks you all python-lovers BTW).

(But please edit out irrelevant parts of the posts you're answering to
!-)
