can someone explain the python code to me, I don't understand

def all_aboard(a, *args, **kw):
    print(a, args, kw)

all_aboard(4, 7, 3, 0, x=10, y=64)

I want to know how this works as the output of the program is

4 (7, 3, 0) {'x': 10, 'y': 64}

How is the code computed?

>Solution :

all_aboard parameters are:

1. a – you already know it
2. *args – any number of parameters which are set as tuple
3. **kw – give you all keyword arguments except for those corresponding to a formal parameter as a dictionary

For this reason the output is:

4 (7, 3, 0) {'x': 10, 'y': 64}

since a = 4, *args = (7, 3, 0) and **kw = {'x': 10, 'y': 64}
