Answer 1

no, when you call such function, you doesn't pass tuple to *arguments nor dictionary to **keywords... except if you unpack them ^^

however, inside the function you receive a tuple in 'arguments' variable and a dictionary in 'keywords' variable (or whatever you call them)...

you call the function with any number of unamed arguments and/or named arguments, and they are packed as tuple/dictionary:

cheeseshop(required, arg1, arg2, key1=val1,key2=val2,key3=val3)

inside function you get:

kind == required
arguments == (arg1, arg2)
keywords == {key1=val1, key2=val2, key3==val3}
