In Python, args is used to pass a variable number of arguments to a function. The asterisk () before the parameter name allows the function to accept any number of positional arguments, which are then passed to the function as a tuple. This means that you can call a function with any number of arguments, and the function will still work correctly. The name "args" is just a convention, and you can use any valid variable name instead. Here is an example of using *args in a function:

def my_func(*args):
    for arg in args:
        print(arg)

        In this example, the function my_func takes any number of arguments and prints them out. You could call this function with any number of arguments, like this:

my_func(1, 2, 3)
my_func('a', 'b', 'c', 'd')
my_func(True, False)

        In each case, the arguments are passed as a tuple to the function, and the function prints them out one by one.
