Master the Art of Flexible Functions with Python's *args and **kwargs ????

Python’s *args and **kwargs offer flexibility and dynamism in your code, allowing you to work with a varying number of arguments in your functions. Let’s dive into these magical constructs! ??

1?? *args: Handling a variable number of non-keyword (positional) arguments. *args is used to pass a variable number of non-keyword (positional) arguments to a function. It allows you to pass any number of positional arguments, which are then bundled into a tuple.

Example:

def sum_numbers(*args):
    result = 0
    for num in args:
        result += num
    return result

print(sum_numbers(1, 2, 3, 4))  # Output: 10        

2?? **kwargs: Handling a variable number of keyword arguments. **kwargs is used to pass a variable number of keyword arguments to a function. It allows you to pass any number of keyword arguments, which are then bundled into a dictionary.

Example:

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

display_user_info(name="John", age=30, city="New York")        

Output:

name: John
age: 30
city: New York        

3?? Combining *args and **kwargs: You can use *args and **kwargs in the same function to accept any combination of positional and keyword arguments:

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

combined_example(1, 2, 3, a=4, b=5, c=6)        

Output:

Positional arguments: (1, 2, 3)
Keyword arguments: {'a': 4, 'b': 5, 'c': 6}        

Embrace the power of *args and **kwargs in your Python code to create more flexible, dynamic, and reusable functions! ??
