Python *args and **kwargs Quiz

Some functions need to take any number of values: a log that records every reading, a launch that accepts optional settings, a helper that passes everything on to another function. In Python, *args collects extra positional arguments into a tuple and **kwargs collects extra keyword arguments into a dictionary. This free quiz has 15 short questions on both, and on * and ** in function calls.

What the quiz covers

• What *args and **kwargs hold inside the function: a tuple and a dictionary
• Mixing regular parameters, *args, default values and **kwargs in one function
• Reading keyword arguments with get() and looping over them with items()
• Unpacking a tuple, a string or a dictionary into a call with * and **
• Passing *args and **kwargs on to another function

How it works

• 15 questions: 11 with one correct answer, 4 where you select every correct answer
• After each question you see the correct answer and a short explanation
• No time limit and no account needed
• Score 70% or more (11 of 15) to pass

You can try each idea in a runnable example: variable arguments with *args, variable keyword arguments with **kwargs, combining argument types and positional and keyword arguments. After this one, try the Python Functions Quiz or the Python Return Values Quiz.
