assertEquals vs. assertEqual in python

Question

Is there a difference between assertEquals and assertEqual in the python unittest.TestCase?

And if there is not, why are there

Answer 1

Not just for Python 3.x, since Python 2.7 assertEquals has been deprecated as well:

Method Name            | Deprecated alias(es)
_________________________________________________________
assertEqual()          | failUnlessEqual, assertEquals

From 25.3.7.1.1. Deprecated aliases
