If what you're trying to do is have more control over the type of
object that is instantiated, then you could use a function that decides

where it then instantiates an object from the chosen class, then
returns the object. The __i
Try running the following example - it should help clear up what is

class Base:
def __init__(self):
print "Initializing base"
def shouldBeImplemented(self):
raise NotImplementedError
def hasDefaultImplementation(self):
print "Wey Hey!"
class A(Base):

it would appear that fromfile and getName are calling the baseClass
methods which are
simple passes What have I done wrong?

def __init__(self, type):
