WebJul 16, 2024 · Short-Circuit Evaluation: Short-circuiting is a programming concept in which the compiler skips the execution or evaluation of some sub-expressions in a logical expression. The compiler stops evaluating the further sub-expressions as soon as the value of the expression is determined. Below is an example of the same: C++ WebIn Python the ___ symbol is used as the equality operator. == Which logical operators perform short-circuit evaluation? or, and What does the following expression mean? x <= y x is less than or equal to y What is the result of the following Boolean expression, given that x = 5, y = 3 and z = 8 x < y and z > x False WebClearly, the interpreter is following the first parenthesization. This is in accordance with the precedence rule for logical operators. The evaluation order is from left to right. But we will return to this in more detail in the section on short circuit evaluation.

Using short-circuiting makes code difficult to read. An if statement clearly communicates that the code should only be run if a condition is fulfilled. But using a logical operator for the same purpose is just confusing.

WebPython always evaluates the left operand before the right- even in function arguments. For expressions with and or operations, it uses short-circuiting. This means it evaluates the second operand only until it is needed. Because of this, such statements can work reliably: Python Operator Precedence – Short Circuiting. WebFeb 28, 2024 · Basically, Python doesn’t evaluate the second condition in the expression unless it has to. This means that for the expression P and Q, Q will only be evaluated if P is true. This makes a lot of sense, since if P is false, P and Q must be false for any Q. Similarly, for the expression P or Q, if P is true we don’t even need to look at Q.
