[Tracker-discuss] [issue664] Value of object is erased when it's called

[Minh Tran Trong]

New submission from Minh Tran Trong <minhtrantrong at gmail.com>:

Please take a look at the image attached. 
I tried to create an object z in memory, then call it with any function, such as  print([e for e in z]) or list(z), after that, z values become empty. 
Is it reasonable design or a bug? I found this appear in both python versions 3.6.5 and 3.7.0
