Python *args and **kwargs

All these tasks involve writing small functions that use *args, **kwargs, or both.

---

*1) Basic args Function

Write a function print_args(*args) that prints all arguments passed to it.

---

*2) Sum Using args

Write a function sum_all(*args) that returns the sum of all numeric arguments.

Example:

sum_all(1, 2, 3) → 6

---

*3) Count args

Write a function count_args(*args) that returns how many arguments were passed.

---

*4) Max Using args

Write a function max_value(*args) that returns the largest number.

---

*5) Min Using args

Write a function min_value(*args) that returns the smallest number.

---

*6) Average Using args

Write a function average(*args) that calculates and returns the average of numbers passed.

---

**7) Greet Using kwargs

Write a function greet(**kwargs) that expects a keyword name and prints:

Hello, <name>!

---

**8) Default in kwargs

Modify greet(**kwargs) so it prints “Hello, Guest!” if no name provided.

---

9) Print All Keys

Write a function print_keys(**kwargs) that prints only the keys passed to it.

Example:

print_keys(a=1, b=2) → prints a, b

---

10) Print All Values

Write print_values(**kwargs) that prints only values.

---

**11) Combine *args and kwargs

Write a function show(*args, **kwargs) that prints both args and kwargs separately.

---

12) Sum With Mixed

Write a function that accepts both *args and **kwargs — sum numeric *args and any numeric **kwargs values.

---

13) Personalized Message

Write:

def message(*args, **kwargs)

so you can call:

message("Welcome", user="Bob")

expected output:

Welcome Bob

---

*14) Count Characters in args

Write a function that takes *args (strings) and prints total character count across all.

---

15) Filter Even Numbers

Write filter_even(*args) returning only even numbers.

---

**16) Update Dictionary Using kwargs

Write a function that accepts a dictionary and **kwargs to update it.

Example:

update_dict({"a":1}, b=2, c=3)

→ results in {"a":1, "b":2, "c":3}

---

*17) Combine Lists in args

Write a function that takes multiple lists via *args and returns one combined list.

---

18) Print Custom Format

Use both *args and **kwargs to print:

Args: <args_tuple>
Kwargs: key1=value1, key2=value2

---

**19) Use kwargs as Settings

Write a function settings(**kwargs) that prints each setting in the format:

setting_name → value

---

*20) Pass args to Another Function

Define a helper function helper(a,b,c) and write another function that uses *args to pass arguments to it.

Example:

helper_args(*[1,2,3]) → helper(1,2,3)

🧠 Concepts Practiced

Topic	What You Learn
Positional variable args	Use of *args
Keyword variable args	Use of **kwargs
Mixed args/kwargs	Functions accepting both
Looping over args	Accessing multiple inputs
Using kwargs values	Accessing named parameters dynamically
Passing through to other functions	Unpacking

📌 Mini Examples

Basic *args:

def print_args(*args):
    for item in args:
        print(item)

Basic **kwargs:

def print_keys(**kwargs):
    for key in kwargs:
        print(key)

Mixing both:

def show(*args, **kwargs):
    print("Positional:", args)
    print("Keyword:", kwargs)
