Adjust the formatting based on the syntax supported by the targeted python versions.

Black uses this option to decide what grammar to use to parse your code. In addition, it may use it to decide what style to use. For example, support for a trailing comma after *args in a function call was added in Python 3.5, so Black will add this comma only if the target versions are all Python 3.5 or higher.
