when to use args and kwargs in python

in python, *args and **kwargs are special syntax that allow you to work with a variable number of arguments in your functions. understanding how to use them can greatly enhance the flexibility and readability of your code. this tutorial will walk you through the basics of *args and **kwargs, when to use them, and provide examples to illustrate their usage.
the *args syntax in a function definition allows it to accept any number of positional arguments. these arguments are packed into a tuple, which can be accessed within the function using the variable name preceded by an asterisk (*).
in this example, the sum_all function accepts any number of arguments, adds them up, and returns the total sum.
similarly, the **kwargs syntax allows a function to accept any number of keyword arguments. these arguments are packed into a dictionary, and you can access the values using the provided dictionary variable name preceded by two asterisks (**).
in this example, the print_info function accepts any number of keyword arguments and prints each key-value pair.
you can use both *args and **kwargs in the same function to make it even more flexible.
in this example, the print_details function can accept both positional and keyword arguments, printing them out accordingly.
understanding how to use *args and **kwargs can make your functions more versatile and adaptable to different use cases. whether you need to handle an unknown number of positional or keyword arguments, these features provide a clean and effective solution. consider using them in your python functions to improve code flexibility and maintainability.
