pythonでPrototype的な実装をしてみる

pythonでprototype.js的な実装をしてみた

#!/usr/bin/env python

# -*- coding: utf-8 -*-
import sys
class Prototype: # Abstract Class

    def __init__(self):

        self.__dict__ = {}
    def __setattr__(self, key, value):

        self.__dict__[key] = value
    def __getattr__(self, key):

        return self.__dict__[key]
    def prototype(self, dict):

        for k in dict:

            v = dict[k]

            self.__setattr__(k, v)
class Function:

    def __init__(): return None
class Class(Prototype, object):

    def __call__(self):

        return self

    def create(self, *args):

        return self


class PrototypeExample:

    def main(*args):

        message = "Hello World!!"
        myClass = Class().create()

        myClass.prototype({

            "message"    : "",

            "initialize" : (

                lambda val :(myClass.__setattr__('message',val))

                ),

            "getMessage" : (

                lambda :(myClass.__getattr__('message'))

                )

            })

        myClass.initialize(message)

        print(myClass.getMessage())
        return 0
if __name__ == "__main__":

    try:

        PrototypeExample().main()

    except Exception, e:

        print("Error Exception!!")

        print(e)
exit(0)

ただ式にいろいろ書けないのがjsやってる人にはつらいですね・・・

ってamachangが実装してたのか！

なるほど！
