# 5 Examples of How to Use Python Tuples in your Code

In this Python Tuples article we want to talk about 5 Examples of How to Use Python Tuples in your Code, so Python tuples are powerful and useful data structure that can be used in  different ways. in this article we want to talk about 5 examples of how to use Python tuples in your code.

## 1. Returning Multiple Values from a Function

One of the most common use cases for tuples is to return multiple values from function. for example let’s say we have a function that performs some calculation and we want to return both the result of the calculation and the amount of time it took to perform the calculation. we can use a tuple to return both values

In the above example perform_calculation() function returns a tuple containing the result of the calculation and the time taken to perform it. after that we unpack the tuple into separate variables using the syntax result, time_taken = perform_calculation().

This will be the result

## 2. Grouping Related Data Together

Tuples can also be used to group related data together. for example let’s say we have a list of 2D points and we want to calculate the distance between each pair of points. we can represent each point as tuple containing its x and y coordinates.

This will be the result

## 3. Immutable Keys in Dictionaries

Python Tuples can be used as keys in dictionaries because they are immutable. this means that once a tuple is created, its contents cannot be changed. let’s say we have a dictionary that maps employee IDs to their names and salaries. we can use tuples to represent each employee name and salary.

This will be the result

## 4. Sorting Sequences

Python Tuples can also be used to sort sequences. let’s say we have a list of 2D points and we want to sort them by their distance from the origin.

This is the result

## 5. Packing and Unpacking Arguments

Tuples can also be used to pack and unpack function arguments. for example let’s say we have a function that takes three arguments.

We can call this function using tuple to pack the arguments.

In this example we have used * operator to unpack the tuple into separate arguments when calling my_function().

This will be the result
