Python Return Multiple Values from Function

Return Multiple Values from Function

We can return multiple values from a function in Python using return statement. The multiple values must be mentioned after return keyword, and the values must be separated by comma.

The syntax to return multiple values, say a, b, and c from a function is

def someFunction():
    #some code
    return a, b, c

In this tutorial, we will learn how to return multiple values from a function in Python, with the help of examples.

Example

In the following program, we write swap() function that can take two arguments, swap the values in the variables, and return both of them.

# Function that returns multiple values
def swap(x, y):
    temp = x
    x = y
    y = temp
    return x, y

# Take two values
a = 10
b = 20
print(f'\nBefore Swap - (a, b)  : ({a}, {b})')

# Swap a, b
a, b = swap(a, b)
print(f'\nAfter  Swap - (a, b)  : ({a}, {b})')

Output

Enter a : 5
Enter b : 9

Before Swap - (a, b)  : (5, 9)

After  Swap - (a, b)  : (9, 5)

Summary

In this tutorial of Python Examples, we learned how to return multiple values from a function, with the help of well detailed example programs.
