Keyword Arguments¶

Let us go through the details related to Keyword Arguments using Python as Programming Language.

Keyword Argument is same as passing argument by name.
You can also specify parameter for varying keyword arguments with ** at the beginning - example: **degrees
While passing arguments to satisfy the parameter with **, you have to pass key as well as value.
Varying Keyword Arguments can be processed as dict in the Function body.

def add_employee(employee_id, **degrees):
    print(f'Length of degrees is: {len(degrees)}')
    print(f'Type of degrees is: {type(degrees)}')
    print(degrees)

add_employee(1, bachelors='B. Sc', masters='M. C. A')

Length of degrees is: 2
Type of degrees is: <class 'dict'>
{'bachelors': 'B. Sc', 'masters': 'M. C. A'}

degrees = {'bachelors': 'B. Sc', 'masters': 'M. C. A'}
add_employee(1, **degrees)

Length of degrees is: 2
Type of degrees is: <class 'dict'>
{'bachelors': 'B. Sc', 'masters': 'M. C. A'}

def add_employee(employee_id, *phone_numbers, **degrees):
    print(f'Length of phone_numbers is: {len(phone_numbers)}')
    print(f'Type of phone_numbers is: {type(phone_numbers)}')
    print(phone_numbers)    
    print(f'Length of degrees is: {len(degrees)}')
    print(f'Type of degrees is: {type(degrees)}')
    print(degrees)

add_employee(1, '1234567890', '1234567890', bachelors='B. Sc', masters='M. C. A')

Length of phone_numbers is: 2
Type of phone_numbers is: <class 'tuple'>
('1234567890', '1234567890')
Length of degrees is: 2
Type of degrees is: <class 'dict'>
{'bachelors': 'B. Sc', 'masters': 'M. C. A'}
