Keyword-Only Parameters After a Bare Star

def resize(image, *, width, height):
    return f"{width}x{height}"

print(resize("photo.png", 800, 600))

What happens when this code runs?

TypeError: resize() missing 2 required keyword-only arguments: 'width' and 'height'

TypeError: resize() takes 1 positional argument but 3 were given

It prints '800x600'

It prints '0x0', since width and height fall back to 0 when not given by keyword
