How do you return values from a function in Python?

Returning Values from Python Functions: Single and Multiple Ways

Python uses the return statement to send values back from a function to the caller. In various ways, a function can return a single value or multiple values.

Returning a single value:

To return a single value from a function, we can simply use the return statement followed by the value you want to return.

Example: Returning a single value

def cube(num):
    return num * num * num
result = cube(3)
print(result)  # Output: 27

Returning multiple values using tuple:

We can return multiple values from a function as a tuple. The values should be separated by commas after the return statement.

Example: Returning multiple values using a tuple

def add_subtract_two_nums(x, y):
    add_result = x + y
    sub_result = x - y
    return add_result, sub_result
result1, result2 = add_subtract_two_nums(25, 9)
print(result1)  # Output: 34
print(result2)  # Output: 16

Returning Multiple Values using a list:

Multiple values can also be returned as a list. Simply put the values in square brackets after the return statement.

Example: Returning multiple values using a list

def get_max_min_value(nums):
    max_value = max(nums)
    min_value = min(nums)
    return [max_value, min_value]
result_list = get_max_min_value([3, 9, 12, 27, 8])
print(result_list)  # Output: [27, 3]

Returning multiple values using a dictionary:

You can return multiple values as a dictionary by using the return statement along with a dictionary.

Example: Returning multiple values using a dictionary

def get_person_details(name, age, city):
    info_dict = {"name": name, "age": age, "city": city}
    return info_dict
result_dict = get_person_details("Zoe Osvaldo", 30, "London")
print(result_dict)  # Output: {'name': 'Zoe Osvaldo', 'age': 30, 'city': 'London'}
