Python’s *args and **kwargs are powerful constructs that allow you to write flexible and versatile functions. They enable you to accept an arbitrary number of arguments, making your code more dynamic and adaptable.

In this article, we’ll dive deep into *args and **kwargs, exploring their syntax, use cases, and code examples.

Understanding *args (Non-Keyword Arguments)

The *args syntax is used to pass a non-keyworded, variable-length argument list to a function. It allows you to pass any number of arguments, and they are collected into a tuple within the function.

def print_numbers(*args):
for arg in args:
print(arg)

print_numbers(1, 2, 3) # Output: 1 2 3
print_numbers(4, 5) # Output: 4 5

In the above example, the print_numbers function accepts any number of arguments using *args. These arguments are then collected into a tuple named args, which can be iterated over or manipulated as needed.

Exploring **kwargs (Keyword Arguments)

The **kwargs syntax is used to pass a keyworded, variable-length argument list to…
