[Python-Dev] Re: Comparison of cyclic objects

[Jeremy Hylton]

Looks like the proposed changed to PyObject_Compare matches E for your
example.  The printed representation doesn't match, but I'm not sure
that is as important.

>>> tight = [1, None, "x"]
>>> tight[1] = tight
>>> tight
[1, [...], 'x']
>>> loose = [1, [1, None, "x"], "x"]
>>> loose[1][1] = loose
>>> loose
[1, [1, [...], 'x'], 'x']
>>> tight
[1, [...], 'x']
>>> tight == loose
1
