This is a simple replacement for the if-else ternary operator. It was added to Python in version 2.5 . x = int (input ("Please enter an integer:\n")) int_type = ('even', 'odd') [x % 2] print (f'You entered {x} which is an {int_type} integer.') Which is Better? The syntax of Python Ternary Operator is where value1 and value2 are the values from which one has to chosen, if and else are keywords, and condition is a boolean expression. symbol for conditional operator. Previous versions may not have the functionality described in this tutorial, as ternary operators were only added in Python 2.5. It performs the action based on whether the given condition is true or false. Simple example of the Python ternary operator in a program. Let's convert the above example to use the ternary operator with a tuple. Phew! Here is an example of ternary operator Let's say we want to return a different string depending on the value of a boolean variable called success. The ternary operator in the following program selects a or b based on the condition a > b evaluating to True or False respectively. Note that the name ternary operator comes from the fact that this operator requires three operands: expression, value1, value2. One way to implement ternary operation in Python is by using a tuple. Through this Python Ternary Operator blog, we tried our best to bring to you all there is to know about the ternary operator in Python. It's a one-liner replacement for the if-then-else statement and is used a lot in Java programming. 2. true_value: The value returned by the ternary operator if the conditional_expression evaluates to True. This operator requires three operands and performs conditional test based on a condition being true or false. This tutorial is based on Python 3.0 and later. We recommend upgrading to the latest version of Python as soon as possible. Are Python ternary operators readable? Syntax of Python ternary operator. The following example shows the usage of the ternary operator in python and also compares its code with the if-else statement. Python supports only one ternary operator. If the result is True, it returns the value_if_true. We were able to run an if statement on one line in the examples above. To understand the difference between the Python ternary operator and the if-else statement method, let's first write the program using the if-else statement. The expression on the right side returns 20 if the age is greater than or equal to 18 or 5 otherwise. The ternary operator analyses a condition before returning a value based on whether the condition is True or False. What is Python ternary operator symbol? The following syntax is called a ternary operator in Python: value_if_true if condition else value_if_false. Dictionary can also be used to create the ternary expression and the syntax for the same is shown below,. Example: condition = True print(2 if condition else 1/0) #Output is 2 print( (1/0, 2) [condition]) #ZeroDivisionError is raised This happens because with the tupled ternary technique, the tuple is first built, then an index is found. Save Article. Explain Python ternary operator with example? If a customer is younger than age 60, they are not eligible for a discount. Conditional operator is also known as Ternary Operator.

Let's write a simple Python program that helps us understand the ternary operator's usage. 2. It simply allows testing a condition in a single line replacing the multiline if-else making the code compact. Example 1: Assigning Variable Using The Ternary Operator When we use the if-else based ternary operator, the condition is evaluated first. . PHP ternary operator example Suppose you want to display the login link if the user has not logged in and the logout link if the user has already logged in. Python ternary operator is the conditional expression to evaluate the statement while programming. The ternary operator includes a condition to evaluate, a true value, and a false value to return based on that condition. Moreover, in comparison to other high-level languages, python code is the most concise and readable. Learn Python Ternary Operator With Examples. Let's see a couple more examples. Ternary . A ternary operator using Dictionary . While Ternary Operators can replace the if-else statement, they are only valid for a single if-else statement. The following syntax is called a ternary operator in Python: >>> def find_max(a,b): return a if (a>b) else b >>> find_max(5, 6) 6 Way to implement Ternary Operator Below are different ways to implement ternary operator. Ternary Expression Syntax. Ternary operators are also known as conditional expressions are operators that evaluate something based on a condition being true or false. We would first write using a normal if-else statement, and then we would use Ternary Operator to best appreciate its usage. if-else or tuple? That's all. Example of Ternary Operator in Python.
