Sorry, you're right! With Python, when you define a function or a class
method like this:
def example(**args):
# do something
you can pass to the example() function many key/value pairs which are
kept as a dictionary. That means that this:
example(a=5, b=10, c="my string")
is passed to the function as a single dictionary args:
args => {a:5, b:10, c:"my string"}
even if you pass it as different single arguments. I don't know the
details on how this mechanism works.
Thank you for your attention...
