class mymut(object):
def __setattr__(self,k,v):
if hasattr(self,k):
if self.__dict__.get(k) == None:
self.__dict__[k] = v
else:
raise TypeError("Cant Modify Attribute Value")
else:
raise TypeError("Immutable Object")
class mm(mymut):
x = ''
y = ''
def __init__(self,x,y):
self.x = x
self.y = y
p = mm(10,11)
print p.x
print p.y
I have created this immutable object.Is there any other better
implementation?
thanks
