if-expr-min-max (FURB136)

Derived from the refurb linter.

Fix is sometimes available.

What it does

Checks for if expressions that can be replaced with min() or max() calls.

Why is this bad?

An if expression that selects the lesser or greater of two sub-expressions can be replaced with a min() or max() call respectively. When possible, prefer min() and max(), as they're more concise and readable than the equivalent if expression.

Example

highest_score = score1 if score1 > score2 else score2

Use instead:

highest_score = max(score2, score1)
