Arbitrary Keyword Arguments

In programming, there's a special syntax for passing any number of named parameters to a function. This syntax is called **kwargs.

**kwargs allows a function to accept any number of named arguments and treat them as a dictionary.


              123456
            
def example_function(**kwargs):
    for key, value in kwargs.items():
        print(f'{key}: {value}')

# Example function call
example_function(name='John', age=25, city='New York')

In this example, **kwargs receives named arguments and prints their keys and values.

Note
The .items() method is used to obtain a list of key-value pairs (items) from a dictionary in Python. Each element in this list is represented as a tuple (key, value).

Tarefa

Fill in the blanks (___) in the function definition so that it can accept a variable number of key-value pairs representing item names and their costs using keyword arguments **kwargs.
Fill in the blanks (___) in the loop to correctly calculate the total cost of the items stored in the **kwargs variable.
