Multiple Return Values

Sometimes it's necessary to return multiple objects as a result of the function. We can do it using two different approaches:

Using a List or Tuple

We can create a list or tuple that contains all necessary objects inside the function and return it as a result of the function.


              123456789101112
            
# Define a function
def return_multiple_objects():
    obj1 = 'Hello'
    obj2 = 42
    obj3 = [1, 2, 3]
	# Return all objects packed into list
    return [obj1, obj2, obj3]
  
# Get the list with corresponding objects
result_list = return_multiple_objects()
for obj in result_list:
	print(obj)

We created three different objects inside the function and returned the list that contains all these objects as an output of the function. Then we iterated this list to get all objects.

Using Multiple Return Values

You can directly return multiple values separated by commas. When function is called, the results are captured in separate variables.


              12345678910
            
def return_multiple_objects():
    obj1 = "Hello"
    obj2 = 42
    obj3 = [1, 2, 3]
	# Return objects separated by comma
    return obj1, obj2, obj3

# Get the result of the function into three different values
result1, result2, result3 = return_multiple_objects()
print(result1, result2, result3)

In the code above we returned three variables separately. If we use this approach it's very important to know the order in which the variables are returned to correctly use them in code.

Create a function that calculates the following data statistics: sum(total), average, minimum and maximum.
Return all values, storing them in separate variables when calling the function.
