Variable-length keyword arguments (**kwargs) in Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a function that accepts any number of keyword arguments.

Python

def greet([1]):
    for key, value in kwargs.items():
        print(f"{key}: {value}")

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using *args instead of **kwargs

Forgetting the ** before kwargs

Using kwargs without ** which is just a normal parameter

Using **kwargs allows the function to accept any number of keyword arguments as a dictionary.

medium

Complete the code to call the function with keyword arguments.

Python

def show_info(**kwargs):
    for key, value in kwargs.items():
        print(f"{key}: {value}")

show_info([1])

Drag options to blanks, or click blank then click option'

A['name', 'Alice', 'age', 30]

B'name', 'Alice', 'age', 30

Cname='Alice', age=30

D(name='Alice', age=30)

💡 Hint

Common Mistakes

Passing arguments as a list or tuple

Passing arguments as strings instead of key=value pairs

Using parentheses around arguments incorrectly

Keyword arguments are passed as key=value pairs when calling the function.

3fill in blank

hard

Fix the error in the function definition to correctly accept keyword arguments.

Python

def details([1]):
    for key, value in kwargs.items():
        print(f"{key}: {value}")

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using single asterisk instead of double

Not using any asterisk

Using *args instead of **kwargs

The function must use **kwargs to accept variable-length keyword arguments.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that filters kwargs with values greater than 10.

Python

filtered = {key: value for key, value in kwargs.items() if value [1] 10 and isinstance(value, [2])}

Drag options to blanks, or click blank then click option'

Cstr

D<

💡 Hint

Common Mistakes

Using less than operator instead of greater than

Checking for string type instead of int

Forgetting to check the type

The comprehension filters keys where the value is an integer greater than 10.

5fill in blank

hard

Fill all three blanks to create a function that prints keys in uppercase and values if they are strings.

Python

def print_strings([1]):
    for key, value in [2].items():
        if isinstance(value, [3]):
            print(f"{key.upper()}: {value}")

Drag options to blanks, or click blank then click option'

D*args

💡 Hint

Common Mistakes

Using *args instead of **kwargs

Not iterating over kwargs

Checking for wrong type

The function accepts keyword arguments as **kwargs, iterates over kwargs, and prints only string values.
