... args kwargs.


Functions in python require arguments and you can be rather expressive with them. You can have functions that accept any number of arguments and there's many nice use-cases to be able to pass around keyword arguments. In this series of videos we'll explore how to use arguments (args) as well as keyword arguments (kwargs).


Notes

Let's have a look at the same function.

def function(a, b, *args, keyword=True, **kwargs):
    print(a, b)
    print(args)
    print(keyword)
    print(kwargs)

Note that this call will fail.

function(a=1, b=2, 5, 3, 4, param=42)

But this one will not.

function(1, 2, 5, 3, 4, param=42)

If you use the rule in the video you may remember why.
