This is pretty hard. For one thing, the object will not be bound to a name until after __init__() is finished. Second, the object may not be bound to a name at all; it could be created and thrown away, or it could be added to a list, dict or other container, it could be a member of another object, it could be a temporary created as a function argument or the return value of a function... Even simple assignment has its complications. The assigned variable can be local or global. The assignment could be via tuple assignment in which case the value is inserted into a temporary tuple, then unpacked and assigned. In the very simple case of x = MyClass() you could probably use the stack frame to find the point of call and inspect the byte codes there to find the name...
