I don’t understand your needs. Since it is a class member variable, it needs to be bound to an instance?
Class variables are shared by all instances, instance variables only belong to the instance

class T:
    def __init__(self):
        self.d = {}
    
if __name__ == "__main__":
    
    t1 = T()
    t2 = T()
    t1.d["a"] = 1
    t2.d["b"] = 2
    print t1.d
    print t2.d
