What is ternary operator in Python with example?

The ternary operator is a way of writing conditional statements in Python. As the name ternary suggests, this Python operator consists of three operands. The ternary operator can be thought of as a simplified, one-line version of the if-else statement to test a condition.

How do you write a ternary operator in Python?

Ternary operators also known as conditional expressions are operators that evaluate something based on a condition being true or false. It was added to Python in version 2.5. It simply allows to test a condition in a single line replacing the multiline if-else making the code compact.

What are the advantage of using ternary operator in Python?

Python ternary operator advantages

Main advantages offered by ternary operator are: It allows us to replace simple if statements with a single line expression. Increases code readability by reducing number of lines of code.

Can we use conditional operator in Python?

Python supports one additional decision-making entity called a conditional expression. (It is also referred to as a conditional operator or ternary operator in various places in the Python documentation.)

Does ternary operator works in Python?

Similarly the ternary operator in python is used to return a value based on the result of a binary condition. ... It takes binary value(condition) as an input, so it looks similar to an “if-else” condition block. However, it also returns a value so behaving similar to a function.

Are ternary operators faster?

Ternary is faster then if/else as long as no additional computation is required to convert the logic to us ternary. When it is a simply ternary operation, it has better readability as well. If only statement is faster than if/else, so if the logic doesn't require an else statement, do use it.

Can you use += in python?

+= adds a number to a variable, changing the variable itself in the process (whereas + would not). Similar to this, there are the following that also modifies the variable: -= , subtracts a value from variable, setting the variable to the result. *= , multiplies the variable and a value, making the outcome the variable.

What is difference between IS and == in Python?

There's a subtle difference between the Python identity operator ( is ) and the equality operator ( == ). The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. ...

Is null in Python?

There's no null in Python; instead there's None . As stated already, the most accurate way to test that something has been given None as a value is to use the is identity operator, which tests that two variables refer to the same object.

How do you write if else in one line?

Example of if…else in one line

1. x = 18. result = 'High' if x > 10 else 'Low' print(result) x = 18 result = 'High' if x > 10 else 'Low' print(result)
2. x = 5. result = 'High' if x > 10 else 'Low' print(result) ...
3. x = 20. result = 10 + 10 if x > 100 else 0. print(result) ...
4. x = 20. result = 10 + (10 if x > 100 else 0) print(result)

How do you write if else in one line Python?

Python if.. elif..else in one line

1. First of all condition2 is evaluated, if return True then expr2 is returned.
2. If condition2 returns False then condition1 is evaluated, if return True then expr1 is returned.
3. If condition1 also returns False then else is executed and expr is returned.

What is ternary operator in Java?

The ternary operator is also known as the conditional operator. This operator consists of three operands and is used to evaluate Boolean expressions. The goal of the operator is to decide, which value should be assigned to the variable.
