Mastering *args and **kwargs in Python

Mastering *args and **kwargs in Python 💡

Python allows functions to accept a flexible number of arguments using *args and **kwargs. This makes your functions more reusable and dynamic. Let's look at some clear examples.

✅ Using *args: multiple positional arguments

*args lets you pass a variable number of positional arguments as a tuple.

def greet(*args):
    for name in args:
        print("Hello,", name)

greet("Alice", "Bob", "Charlie")

✅ Using **kwargs: multiple keyword arguments

**kwargs collects keyword arguments as a dictionary.

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

introduce(name="Alice", age=25, job="developer")

✅ Combining both *args and **kwargs

You can even use both in one function to maximize flexibility.

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

process(1, 2, 3, name="Alice", role="admin")

These tools are essential when building libraries, decorators, or APIs. Learn them once, use them everywhere!
