        “*args

        *args is a special syntax used in function definition to pass variable-length argument.
        “*” means variable length and “args” is the name used by convention. You can use any other.
        def multiply(a, b, *argv):
        mul = a * b

        for num in argv:
        mul *= num

        return mul

        print(multiply(1, 2, 3, 4, 5)) #output: 120
        **kwargs

        **kwargs is a special syntax used in function definition to pass variable-length keyworded argument.
        Here, also, “kwargs” is used just by convention. You can use any other name.
        Keyworded argument means a variable which has a name when passed to a function.
        It is actually a dictionary of variable name and its value.
        def tellArguments(**kwargs):
        for key, value in kwargs.items():
        print(key + “”: “” + value)
        tellArguments(arg1 = “”argument 1″”, arg2 = “”argument 2″”, arg3 = “”argument 3″”)
        #output:
        # arg1: argument 1
        # arg2: argument 2
        # arg3: argument 3″

        #18479
