Arbitrary Keyword Arguments

In programming, there is a special syntax for passing any number of named parameters to a function, known as **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 from a dictionary in Python. Each element in this list is represented as a tuple (key, value).
