Are one line if statements faster Python?

I would say the single test is as fast as the separate tests. Python also makes use of so called short-circuit evaluation. That means for (a and b and c) , that b or c would not be tested anymore if a is false . Similar, if you have an OR expression (a or b) and a is true , b is never evaluated.

There are two ways of writing a one-liner for loop:

Does Python have a ternary conditional operator?

edited Jun 2, 2019 by Shrutiparna @Ayush Yes , Ternary operator is available in Python from version 2.5. It’s a conditional operator which performs an operation based on a condition being true or false in a single line test instead of multiline if-else complexity. It has the lowest priority of all other python operators.
