*args and **kwargs

Similar to the char* and char** difference in C. If you have a function that accepts *args, the things you inputtedargs will then be packed into a tuple.

def print_args(*args):
    print(args)

print_args(1, 2, 3, "hello", "world", "hello, world")
# output: (1, 2, 3, 'hello', 'world', 'hello, world')

And **kwargs are like the C **argv, you can provide a key to the argument you pass (hence the shortened name **kwargs meaning Key Word Arguments)

def print_kwargs(**kwargs):
    print(kwargs)

print_kwargs(a="a", one=1, b="b", two=2)
# output: {'a': 'a', 'one': 1, 'b': 'b', 'two': 2}

Note that *args and **kwargs are just naming conventions, you can still name them to anything as long as it’s in the rules of naming within Python.
