Python In Practice - 15 Projects to Master Python - Arbitrary Keyword Arguments (**kwargs)

The video tutorial explains how to handle keyword arguments in Python functions using double stars (**kwargs). It demonstrates creating a function that accepts any number of keyword arguments, which are stored as a dictionary. The tutorial covers implementing a loop to iterate over the dictionary and print key-value pairs. It also addresses common errors, such as 'too many values to unpack', and suggests using the items() function to resolve them. Finally, the video shows how to run the program and observe the results, highlighting the flexibility of using keyword arguments.

What is the purpose of using double stars (**) in a function definition?

• To receive a fixed number of arguments

• To return multiple values from a function

• To define a function with no parameters

• To receive an unspecified number of keyword arguments

What data structure is used to store keyword arguments passed to a function?

• Dictionary

• Set

• Tuple

• List

Which function is necessary to use when iterating over a dictionary to avoid errors?

• keys()

• values()

• items()

• get()

What happens if no keyword arguments are passed to a function that uses **kwargs?

• The function requires default values

• The function executes without error

• The function returns None

• An error is raised

How does the function handle different numbers of keyword arguments?

• It raises an error if more than three arguments are passed

• It only accepts arguments defined in the function

• It requires all arguments to be passed as a list

• It can handle any number of arguments, including zero
