It is not so much using __init__() that makes the difference as it what scope the variables are assigned to. If you define them as you where, then the variables are associated with the class object itself. If the variable is a mutable type, and you change it in one instance, it actually changes it in the class object which means it also changes for all of the instances. I used the constructor because it gives me a reference to the newly created instance object "self". I then assign the variables to self, which assignes them to the newly created instance object. Then each instance has its own separate a and b variables that will not change when the variables are changed inside of another instance object. -- http://mail.python.org/mailman/listinfo/python-list
