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

The example below contains the call that is able to unpack both the *args as well as the **kwargs.

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

d = {'param_a': 43, 'param_b': 44}
function(1, 2, *[5, 3, 4], param=42, **d)

Feel free to play with the code until you understand the print statements. Pay attention to the symmetry between * and ** arguments.
