Introduce isort to automate import ordering and formatting Similar to the recent adoption of Black. isort is a Python utility to sort imports alphabetically and automatically separate into sections. By using isort, contributors can quickly and automatically conform to the projects style without thinking. Just let the tool do it. Uses the configuration recommended by the Black to avoid conflicts of style. Rewrite TestImageQt.test_deprecated to no rely on import order. 2019-07-06 23:40:53 +03:00			`from io import BytesIO`

Rather than convert strings literals to bytes at runtime, simply use a bytes literal. 2019-10-07 05:26:55 +03:00			`Image.open(BytesIO(b"\x00\x00\x00\x0cjP\x20\x20\x0d\x0a\x87\x0a\x00\x00\x00\x00hang"))`
