cirq.testing.only_test_in_python3(func)

A decorator that indicates a test should not execute in python 2.

For example, in python 2 repr(‘a’) is “u’a’” instead of “‘a’” when

from future import unicode is present (which it will be, since 3to2

inserts it for us). This is annoying to work around when testing repr

methods, so instead you can just tag the test with this decorator.
