In this tutorial, we will learn how to use Ternary Operator in Python. It takes binary value (condition) as an input, so it looks similar to an “if-else” condition block. The ternary conditional operator is a short-hand method for writing an if/else statement. The expression x if C else y first evaluates the condition, C rather than x . Ternary operators in Python are terse conditional expressions. It was added to Python in version 2.5. We have trained over 90,000 students from over 16,000 organizations on technologies such as Microsoft ASP.NET, Microsoft Office, Azure, Windows, Java, Adobe, Python, SQL, JavaScript, Angular and much more. Many programming languages have a ternary operator, which define a conditional expression. It simply allows to test a condition in a single line replacing the multiline if-else making the code compact. So, let’s see how to use if-else in one line, if..else in a single line in python like a ternary operator. a=10 print("a is 10") if a==10 else print("a is not 10") Output: a is 10 Ternary if else. In the below example, the idea is to check whether the value of sum is less than or greater than 50. num1 and num2 are initialised with values 100 and 20 respectively which are assigned to sum variable by adding them. Conditional expressions (sometimes called a “ternary operator”) have the lowest priority of all Python operations.

If it’s Even then, it goes to check whether it is a multiple of four or not. The reason for that is if expression is true, the interpreter will check for the on_true, if that will be zero or false, that will force the interpreter to check for on_false to give the final result of whole expression. :) in JavaScript? This operator, if used properly, can reduce code size and enhance readability. But if you are confused with value returned is of ‘a’ or ‘b’. Welcome to another Python snippet post. Addition. Many programming languages support ternary operator, which basically define a conditional expression. operator.attrgetter (attr) ¶ operator.attrgetter (*attrs) Return a callable object that fetches attr from its operand. This is similar like if else statements, Ternary operator is nothing but conditional expressions which is used to assign expression result based on condition. Python ternary operator was introduced in Python 2.5. How to solve the problem: Solution 1: Yes, it was added in version 2.5. Similarly the ternary operator in python is used to return a value based on the result of a binary condition. It works upon, where the result of an expression (conditional expression) depends on the True or False value. How can we use Python Ternary Operator Without else? But in python, we can use the if-else in a single line, and it will give the same effect as the ternary operator.

It makes your code look cleaner and compact. Here is a blueprint and an example of using these conditional expressions. 2. In an expression like the one given below , the interpreter checks for the expression if this is true then on_true is evaluated, else the on_false is evaluated. You may know the ternary operator x if c else y in Python which reads as "return x if c else return y". With ternary operator, we are able to write code in one line. In many Python circles, the ternary operator is also called “conditional expression” because it executes a given expression only if a condition is met. Similarly the ternary operator in python is used to return a value based on the result of a binary condition.
