对象中的PHP和Python静态方法，两个不同的世界......？

Question

i'm php coder, trying to get into python world, and it's very hard for me.

Biggest enjoy of static methods in php is automatic builder of instance. No need to declare object, if you needed it once, in every file (or with different constructor params , in one line)

<?php
class Foo { 
    function __constructor__(){
        $this->var = 'blah';
    }
   public static function aStaticMethod() {
       return $this->var;
   }
}

echo Foo::aStaticMethod();
?>

we can call constructor from static method don't we? and we can access everything in class as it would be simple method ... we can even have STATIC CONSTRUCTOR in php class and call it like so: Object::construct()->myMethod(); (to pass different params every time)

but not in python???? @staticmethod makes method in class a simple function that doesn't see totally anything ??

class socket(object):

def __init__(self):
    self.oclass = otherclass()
    print 'test' # does this constructor called at all when calling static method??                

@staticmethod
def ping():
    return self.oclass.send('PING') # i can't access anything!!!


print Anidb.ping()

I can't access anything from that god damned static method, it's like a standalone function or something like this..??

Maybe I'm using the wrong decorator? Maybe there's something like php offers with static methods in python?

1) Please tell why static methods is isolated 2) Please tell me how to make the same behavior like php static methods have. 3) Please tell me alternative practical use of this, if php static methods behavior is a bad thing

P.s. the goal of all this to write totally less code as much as possible. P.p.s Heavy commenting of sample code is appreciated

Thank you.

I see you've already accepted another answer, but I'm not sure that it will work with your code. Specifically, the oclass variable is only created for instances of the class, not for the class itself. You could do it like this:

class socket(object):
    oclass = otherclass()                

    @classmethod
    def ping(cls):
        return cls.oclass.send('PING')

socket.ping()

However, using your existing code and removing all decorators, you could simply instantiate it and use a method on the same line:

socket().ping()
