newsuper 0.2a

Py3k-alike style super() for Py2.x

Intro

newsuper provides you Python3k-alike super() for Python2.x,

Why

you must hate to write code like this:

super(Foo, self).__init__()

and you might have written (WRONG) code like this:

super(self.__class__, self).__init__()

Python3k’s super() saves your ass a bit:

super().__init__()

but this looks evil, and confusing for classmethods

Example

You can make your topest-level class subclassing newsuper.Object

from newsuper import Object

class Foo(Object):
    def __init__(self):
        self.foo = 1

    @classmethod
    def do_something(cls):
        return ['Foo']

class Bar(Foo):
    def __init__(self):
        super().__init__(self) # You should pass self explictly
        self.bar = 1

    @classmethod
    def do_something(cls):
        return super().do_something() + ['Bar']

class Baz(Bar):
    def __init__(self):
        super().__init__(self)
        self.baz = 1

    @classmethod
    def do_something(cls):
        return super(Baz, cls).do_something() + ['Baz'] # Compatible with old super(Baz, cls)

if __name__ == '__main__':
    assert Baz().foo == Baz().bar == Baz().baz == 1
    assert Baz.do_something() == ['Foo', 'Bar', 'Baz']

property is supported too.

Warning

There is difference between newsuper and Python3k super()

in Python3k, super().method() == super(Foo, self).method()

In newsuper, super() always returns a proxy of class, not instance

in other words, you must pass self by yourself!

Install

Let’s try it now

Use pip:

pip install newsuper

or easy_install:

easy_install newsuper

also, there is windows installer.
