How To Use Ternary Operator in Python With Examples

Python is a must-have programming language in today's world. The popularity of Python is growing by the day. Students are often perplexed by basic Python concepts such as tuples in Python and Python linked lists, ternary operators, etc. So many kids turn to the internet for help. As a result, we shall examine the ternary operator in Python with programs in this blog. Continue reading to get answers to your questions about ternary operators in Python.

Let's start with a definition of ternary operators.

In Python, the ternary operator determines if a condition is true or false. The ternary operator is more compact than a whole if-else expression because it only takes one line of code.

Conditional statements, such as if statements, can be used to control the flow of your program. The code inside conditional expressions executes when a given condition (or a set of events) is met.

The if the keyword is the most common way to write a conditional statement in Python. On the other hand, the ternary operator enables you to test a condition on a single language line. Let's go through the basics of conditional statements in Python and how to use the ternary operator.

Conditionals in Python

When writing a program, you may only want a line or a block of code to be executed when a condition is met. Conditional statements can be used to accomplish this operation in Python.

In Python, the if statement is used to check if a condition satisfies the intended result. Assume we develop an app that assesses whether or not a customer is eligible for a 20% discount at a department store. Customers who are 60 years old or older should be given a discount. He should not be given a discount if this is not the case. The if-else statement can be used to generate this program in this case. The ternary operator in Python provides a more efficient way to express an if statement if you need to assess a few criteria.

Python's ternary operator

It simply substitutes the multiline if-else condition testing with a single line, making the code more compact.

Syntax

[when true] otherwise if [expression] [when false]

The Ternary Operator is used to return a value.

We can also use ternary operators in the return statement within our functions. For example, we may create a function that checks if a number is even or odd and returns the text 'even' or 'odd':

When performing ternary operations, a tuple is used.

In Python, a tuple is another way to do ternary operations. This is a straightforward replacement for the ternary operator if-else.

False value and true value are the two members of the Tuple in this scenario. The conditional expression is placed in square brackets instead of an index. Because True has a value of 1 and False has a value of 0, this works.

As a result, its value is if the conditional expression evaluates to True.

The ternary expression then returns the element at index 1. If the conditional statement evaluates to False, its value becomes 0. After that, the element with index 0 is returned.

Points to Remember: 

• The order of the parameters in the operator differs from that of other languages.

• Conditional expressions are the least important of all Python actions.

• The Python ternary operator can be used to perform simple if statements more rapidly. Before returning a value based on whether a condition is True or False, the ternary operator examines it.

• In the instances above, we were able to run an if statement on a single line. This is more compact than an if statement, which generally requires several lines. On the other hand, the ternary operator cannot always be used in Python. To test for multiple expressions, you should create an entire if statement. This will make your code easier to read and comprehend.

Conclusion

This brings us to the information's conclusion. We learned how to use Python's ternary operator in various ways. We've seen how ternary operators improve the readability and compactness of code.
