**kwargs

Similar to *args, we use **kwargs to pass a variable number of named arguments. Similar to *args, if we put ** in front of a name, the name will accept any number of named arguments. A dictionary of several passed arguments will be available under this name. Let's look at the example.

def grocery_cart(price_of_apples, **prices_of_other_fruits):
print(price_of_apples)
for value in prices_of_other_fruits.values():
print(value)

grocery_cart(price_of_apples = 10, price_of_oranges = 7, price_of_carrots = 12)

              
123456

            
def grocery_cart(price_of_apples, **prices_of_other_fruits):
    print(price_of_apples)
    for value in prices_of_other_fruits.values():
        print(value)

grocery_cart(price_of_apples = 10, price_of_oranges = 7, price_of_carrots = 12)

To sum up Arbitrary Arguments:

  • use a single asterisk (*) to unpack iterables.

  • and use 2 asterisks (**) to unpack dictionaries.

Tâche

Swipe to start coding

Code a function, named function, that will take in an unknown number of named arguments. This function runs for each argument using the for loop and prints only those longer than 6 characters.

Solution

def function(**variables):
for x in variables.values():
if len(x) > 6:
print(x)
function(name="Max", town="London", language="English")
