Question

Is there a “synonym” for attr_readerin python, like something that doesn’t have to make me type out?:

class Foo():
    def __init__(self, foo, bar, spam, spammity, spam, spam, quux, foobar, barfoo):
        self.foo = foo
        self.bar = bar
        self.spam = spam
        # And so on...

Just a one line thing that makes self.foo = foo, etc., sort of like how ruby’s attr_reader would make

@foo = foo

Answer 1

You can do this with kwargs:

class Foo():
  def __init__(self, **kwargs):
    self.foo = kwargs['foo']

And you pass in named arguments:

foo = Foo(foo='bar')

Of course, you might want to catch KeyError exception
