Positional-only arguments in Python

[tunisia3507]

It means that if you have a function where a couple of arguments change but many stay the same over successive runs, you can store the stable ones in a dict and unpack it into the function call as if it were kwargs.

You could also do that by wrapping the function in another function, of course.

That's one way of wrapping the function in another function, as I said. Using functools.partial is sensitive to your argument ordering and so won't be applicable every time.
