But shouldn't DeprecationWarning be in the following case as well?
$ cat a.py def f(s): return s != "hello \world" $ cat b.py import a print(a.f("xxx")) $ python b.py True $ python -W error b.py Trueserhiy-storchaka commentedon Oct 4, 2016
See bpo-28128.
A warning should be emitted when you compile the code, but it shouldn't be emitted when you import compiled module.
