Python: Generic getters and setters

Question

TL;DR: Having to define a unique set of getters and setters for each property()\'d variable sucks. Can I define generic getters and setters and use them with whatever

Answer 1

How about just:

def sasquatchicorn(name):
    return property(lambda self: getattr(self, name) + ' sasquatch',
                    lambda self, val: setattr(self, name, val + ' unicorns'))

class Foo(object):
    bar = sasquatchicorn('_bar')
    baz = sasquatchicorn('_baz')

Somewhat more generically:

def sasquatchify(val):
    return val + ' sasquatch'

def unicornify(val):
    return val + ' unicorns'

def getset(name, getting, setting):
    return property(lambda self: getting(getattr(self, name)),
                    lambda self, val: setattr(self, name, setting(val)))

class Foo(object):
    bar = getset('_bar', sasquatchify, unicornify)
    baz = getset('_baz', sasquatchify, unicornify)

Or, with barely more work, you can use the full descriptor protocol, as described in agf's answer.
