Why not simply result = (y, x)[a < b] Why do you uses lambda function ?

@GrijeshChauhan Because on "compliated" expressions, e. g. involving a function call etc., this would be executed in both cases. This might not be wanted.

The use of lambda functions is an overkill for this question

@GrijeshChauhan In short, this implements the so-called “short-circuit evaluation”. Generally, P ? x : y or x if P else y can be written as (lambda:y, lambda:x)[P]() — but I doubt it has better performance and thus its necessity.
