Kargs

Kargs, short for keyword arguments, is a concept found in many programming languages, notably Python. It refers to arguments passed to a function that are explicitly identified by their parameter name, rather than their position. This contrasts with positional arguments, where the order of the arguments determines which parameter they are assigned to.

Using kargs offers several advantages. Firstly, it improves code readability and clarity, as it's immediately obvious which value corresponds to which parameter, especially when a function has many parameters or optional parameters. Secondly, it allows for arguments to be passed in any order, as the parameter name dictates the assignment. This is particularly useful when dealing with functions that have a large number of optional parameters, as the caller only needs to specify the ones they wish to change.

In Python, kargs are implemented using the double-asterisk syntax (**) within function definitions and calls. When defining a function, **kwargs collects any keyword arguments that are not explicitly defined as parameters into a dictionary. When calling a function, **kwargs can be used to unpack a dictionary of keyword arguments. This flexibility makes kargs a powerful tool for writing more robust and maintainable code.
