Python Return Function

We can return the result or output from the function using a 'return' statement in the body of the function. For example,

return c #returns c value out of function

return 100 #returns 100

return lst #return the list that contains values

return x, y, c #returns 3 values

A Python program to find the sum of two numbers and return the result from the function.

A function to test whether a number is even or odd.

A Python program to calculate factorial values of numbers.

Returning Multiple Values from a Function

A function returns a single value in the programming languages like C or Java. But in Python, a function can return multiple values. When a function calculates multiple results and wants to return the results, we can use the return statement as:

return a, b, c

Here, three values which are in 'a', 'b' and 'c' are returned. These values are returned by the function as a tuple. Please remember a tuple is like a list that contains a group of elements. To grab these values, we can use three variables at the time of calling the function as:

x, y, z = function()

def sum_sub(a, b):

c = a + b

d = a - b

d = a - b

return c, d

A function that returns the results of addition, subtraction, multiplication and division.

A function that returns the results of (a+b)2, (a-b)2, (a+b)3, (a-b)3.
