Swap If Expression

Sourcery refactoring id: swap-if-expression

Description

Swap the if and else branches of an if-expression to remove a negation

Before

my_hat = hats.bowler if not weather.is_sunny() else hats.baseball_cap

After

my_hat = hats.baseball_cap if weather.is_sunny() else hats.bowler

Explanation

Negated conditions are more difficult to read than positive ones, so it is best to avoid them where we can. By swapping the if and else conditions around we can invert the condition and make it positive.
