Hello, in an example in https://docs.python.org/3.8/library/unittest.html#skipping-tests-and-expecte... One could read @unittest.skipIf(mylib.__version__ < (1, 3), "not supported in this library version") However, PEP 396 indicates "__version__ number SHOULD be a string", therefore the example is against a good python practice, and package manager like me would loose time googling the what the good practice is. I suggest changing the example to skipIf(mylib.version_info < (1, 3), ...).
