[Python-ideas] PEP 8 update on line length

[Jonathan Fine]

Raymond Hettinger posted a helpful example to this list. Here, I run
his example, and a variant, through https://black.now.sh

Raymond
class Frabawidget:

    @wozzle.setter
    def wibble(self, woozle):
        if not (self.min_woozle < woozle < self.max_woozle):
            raise ValueError(f"Expected woozle to be between
{self.min_woozle} and {self.max_woozle}")
        self._wozzle = normalize(woozle)

black.py
class Frabawidget:
    @wozzle.setter
    def wibble(self, woozle):
        if not (self.min_woozle < woozle < self.max_woozle):
            raise ValueError(
                f"Expected woozle to be between {self.min_woozle} and
{self.max_woozle}"
            )
        self._wozzle = normalize(woozle)

Raymond variant
class Frabawidget:

    @wozzle.setter
    def wibble(self, woozle):
        if not (self.min_woozle < woozle < self.max_woozle <
self.super_max_value) and do_this_or_that_():
            raise ValueError(f"Expected woozle to be between
{self.min_woozle} and {self.max_woozle}")
        self._wozzle = normalize(woozle)

black.py
class Frabawidget:
    @wozzle.setter
    def wibble(self, woozle):
        if (
            not (
                self.min_woozle
                < woozle
                < self.max_woozle
                < self.super_max_value
            )
            and do_this_or_that_()
        ):
            raise ValueError(
                f"Expected woozle to be between {self.min_woozle} and
{self.max_woozle}"
            )
        self._wozzle = normalize(woozle)

(By the way, I had to add the 'wibble' to the code above, to avoid a
syntax error.)
