Hi All, Here is a sample piece of code with which I am having a problem, with Python version 2.4.4
class Person: Count = 0 # This represents the count of objects of this class def __init__(self, name): self.name = name print name, ' is now created' Person.Count += 1 def __del__(self): print self.name, ' is now deleted' Person.Count -= 1 if Person.Count == 0: print 'The last object of Person class is now deleted' else: print 'There are still', Person.Count, ' objects of class Person' x2 = Person("Krishna") del x2 When the above code is executed, it works properly. If the last statement del x2, is removed, then when the program terminates, this throws up an exception as shown below Krishna is now created Krishna is now deleted Exception exceptions.AttributeError: "'NoneType' object has no attribute 'Count' " in <bound method Person.__del__ of <__main__.Person instance at 0xf6532f6c>> ignored Can someone please explain why the exception happens in the case where there is no explicit del statement?
