Hello All,
Can someone explain why 2 objects in the following statements give me the
same id() value?
>>> A, B = symbols('A B', commutative=False)
>>> x = A*B
>>> print id(x)
169853492
>>> y = A*B
>>> print id(y)
169853492
I run into this problem while trying to implement some operation on Trace
module.
Say, I have Tr(A*B*C) . Now, the user wants to create another instance of
Tr(C*A*B). But, both objects are getting the same id, meaning I am not
able to create 2 different objects one which prints at Tr(A*B*C) and
another which prints as Tr(C*A*B). Note, that I have not yet overridden
_hashable_contents to compare the args ( using the cyclic property of
trace).
Am I missing something basic? Or is there a way to override this
behavior, if necessary
Thanks
Guru
