No. See the library reference manual: "If both comparands are aware, and have the same tzinfo attribute, the common tzinfo attribute is ignored and the base datetimes are compared." <https://docs.python.org/3/library/datetime.html>

The reasons for this have been explained at length in the recent Datetime-SIG discussions. Please check the archives if you are interested: <https://mail.python.org/pipermail/datetime-sig/2015-August/000169.html>.
