What type of argument in a Python function is passed by name instead of position?Keyword ArgumentDefault ArgumentRequired ArgumentVariable-length Argument

The type of argument in a Python function that is passed by name instead of position is called a Keyword Argument.

Explanation

In Python, when you define a function, you can call it in two main ways: by using postional arguments or by using keyword arguments.

1. Keyword Arguments: These are arguments that are specified by name during a function call. For instance, if you have a function defined as def func(a, b):, you can call it using func(b=2, a=1), specifying the names of the parameters explicitly. This allows the caller to pass the arguments in any order.

2. Default Arguments: These are parameters that have a predefined value. If a value is not provided for such an argument during the function call, the default value is used.

3. Required Arguments: These are parameters that must be provided during the function call; otherwise, Python will raise an error.

4. Variable-length Arguments: This feature allows you to pass an arbitrary number of arguments to a function. It is implemented using *args (for non-keyword variable arguments) and **kwargs (for keyword variable arguments).

In summary, while keyword arguments are specifically named and allow flexibility in argument order, the other types of arguments have their own distinct characteristics.
