Hi everyone. Quick question here. Lets suppose if have the following numpy array: b=np.array([[0]*2]*3) and then: >>> id(b[0]) 45855552 >>> id(b[1]) 45857512 >>> id(b[2]) 45855552 Please correct me if I am wrong, but according to this b[2] and b[0] are the same object. Now, >>> b[0] is b[2] False Any clarification is much appreciated. Cheers,
