Simplest:
class Base(object):
def __init__(self, attr):
self._attr = attr
def getattr(self):
return self._attr
@property # single-arg property is a read-only thing.
def attr(self):
return self.getattr()
### Little longer; maybe more explicit (tastes vary):
class Base(object):
def __init__(self, attr):
self._attr = attr
def getattr(self):
return self._attr
def attr(self):
return self.getattr()
attr = property(fget=attr)
