Or,How to use variable length argument lists in Python. The special syntax,*argsand**kwargsin function definitions is used to pass a variable number of arguments to a function. The single asterisk form (*args) is used to pass anon-keyworded, variable-length argument list, and the double ...
By: Rajesh P.S.In Python, *args and **kwargs are special syntax used in function definitions to handle a varying number of positional and keyword arguments, respectively. They provide flexibility when defining functions that can accept a variable number of arguments without having to explicitly ...

Like*args,**kwargscan take however many arguments you would like to supply to it. However,**kwargsdiffers from*argsin that you will need to assign keywords. First, let’s print out the**kwargsarguments that we pass to a function. We’ll create a short function to do this: print_kwa...
In this article, we’ll learn about *args and **kwargs, two special Python symbols that you may have probably encountered in some function signatures before. The title is kind of a spoiler: *args and…
Master Python for data science and gain in-demand skills. Start Learning for Free Assigning functions to variables To kick us off we create a function that will add one to a number whenever it is called. We'll then assign the function to a variable and use this variable to call the func...
That can come in handy, but with the particular function we’ve written here it’s most clear to use all positional arguments or all keyword arguments. Why use keyword arguments? When calling functions in Python, you’ll often have to choose between using keyword arguments or positional argumen...
Here’s a basic explanation of how you can create a function in Python: Syntax: def function_name(parameter1, parameter2, …): # Function body – where you write the code that the function executes # Use parameters to perform operations # Optionally, return a value using the ‘return’...
expressions, check out How to Use Generators and yield in Python. Map The built-in functionmap() takes a function as a first argument and applies it to each of the elements of its second, an iterable. Examples of iterables are strings, lists, and tuples. For more information on...
Function arguments are handy, but some functions can benefit from accepting a variable number of arguments. Named keyword arguments can make your code more readable and easier to use. You should embrace Python's *args and **kwargs arguments. They are pretty simple to use, and with them, you...
