# Return Multiple Values From a Function in Python

Functions are an essential part of any programming language. A function is a block of code that can be called to perform a specific operation in programming. Usually, a function is used to return a value. This value can be a number, a string, or any other datatype.

In this tutorial, we will discuss different methods to create a function that returns multiple values. We will return different data objects like a list, a dictionary, and other objects from a user-defined function to achieve this.

## Use a Tuple to Return Multiple Values From a Function in Python

If we return values from a function separated by a comma, they are considered a tuple. Tuples are usually enclosed in parenthesis. In the code below, we will return a tuple from a Python function.

``````def return_multi(a):
b = a+1
c = a+2
return b, c

x = return_multi(5)
print(x,type(x))
``````

Output:

``````(6, 7) <class 'tuple'>
``````

## Use a List to Return Multiple Values From a Function in Python

Python lists are used to store different items under a common name and at specific positions. Functions can also return multiple values in a list, as shown below.

``````def return_multi(a):
b = a+1
c = a+2
return [b,c]

x = return_multi(5)
print(x,type(x))
``````

Output:

``````[6, 7] <class 'list'>
``````

## Use a Dictionary to Return Multiple Values From a Function in Python

Dictionaries are used to store key-value pairs in Python. We can have the final output in a much more organized format by returning a dictionary from a function with keys assigned to different values. See the following example.

``````def return_multi(a):
b = a+1
c = a+2
return {'b':b,'c':c}

x = return_multi(5)
print(x,type(x))
``````

Output:

``````{'b': 6, 'c': 7} <class 'dict'>
``````

## Use a Class to Return Multiple Values From a Function in Python

Classes contain different data members and functions and allow us to create objects to access these members. We can return an object of such user-defined classes based on the class structure and its data members. For example:

``````class return_values:
def __init__(self, a,b):
self.a=a
self.b=b

def return_multi(a):
b = a+1
c = a+2
t=return_values(b,c)
return t

x = return_multi(5)
print(x.a,x.b,type(x))
``````

Output:

``````6 7 <class '__main__.return_values'>
``````

## Use a `dataclass` to Return Multiple Values From a Function in Python

A `dataclass` is a new interesting feature added in Python v3.7 and up. They are similar to traditional classes but mainly used to store data and all their basic functionalities are already implemented. The `@dataclass` decorator and the `dataclass` module are used to create such objects. In the code below, we return a `dataclass` from a function.

``````from dataclasses import dataclass

@dataclass
class return_values:
a: int
b: int

def return_multi(a):
b = a+1
c = a+2
t= return_values(b,c)
return t

x = return_multi(5)
print(x.a,x.b,type(x))
``````

Output:

``````6 7 <class '__main__.return_values'>
``````
