I checked python operator precedence

Operators in the same box group left to right (except for exponentiation and conditional expressions, which group from right to left).

** Exponentiation [5]

if – else Conditional expression

I can understand exponentiation that 2**3**2 is equal to 2**(3**2). But Conditional expression

conditional_expression ::= or_test ["if" or_test "else" expression]

is not one binary operator. I can't give one similar example as **. Could you give one example of "group from right to left" for if Conditional expression?
